显示键盘时向上推除某些视图之外的内容

Push up content except some view when keyboard shown

我的布局在底部包含 5 个 EditText 和一个 Button 以及一个 TextView。现在,当我按下 EditText 时,键盘将显示并且 all 我的 View 被向上推。

现在我不想把我的 TextViewButton 推到键盘上方,只想 全部推上去 EditText 里面 ScrollView 到键盘上方。

<?xml version="1.0" encoding="utf-8"?>

            >

            <EditText
                android:layout_marginTop="30dp"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="EditText 1"

                />

            <EditText
                android:layout_marginTop="30dp"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="EditText 2"
                />

            <EditText
                android:layout_marginTop="30dp"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="EditText 3"
                />

            <EditText
                android:layout_marginTop="30dp"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="EditText 4"
                />

            <EditText
                android:layout_marginTop="30dp"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="EditText 5"
                android:inputType="textNoSuggestions"
                />

        </LinearLayout>

    </ScrollView>

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:text="Button"
        />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#000"
        android:text="I don't want to push this TextView and Button to above keyboard when keyboard is shown. Just obly want to push the ScrollView that contain all EditText"
        />
</LinearLayout>

我有个想法是。当键盘显示和隐藏时我会监听。当键盘显示时,我将设置 ScrollView 的底部边距 = 键盘高度,当键盘隐藏时,我将设置此边距 = 0.
有什么方法更容易处理我的案子吗?任何帮助或建议将不胜感激。

更新
如果我使用 windowSoftInputMode=adjustPan => 并非所有 EditText 都被推到键盘上方
如果我使用 windowSoftInputMode=adjustResize => ButtonTextView 并且所有 EditText 都被推到键盘上方

不起作用 - 没有可靠的 API 来检测何时显示键盘。您会在此站点上看到 "solutions",但它们有误报和漏报。但似乎对您来说最好的办法是将 softInputMode 设置为 adjustPan。这将使 OS 滚动整个屏幕所需的最小量,使光标在键盘上方可见。 (整个应用程序在键盘上方是由于模式 adjustResize)。

您必须在您的 Manifest 中添加 android:windowSoftInputMode="adjustPan",它将像 Pro 一样工作:

<activity android:name=".your_activity_name"
        android:windowSoftInputMode="adjustPan">
    ..............

</activity>

请尝试添加此布局,

 <LinearLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@+id/activity_main"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:orientation="vertical">
<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1"
    android:background="#ff0"
    >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        >

        <EditText
            android:layout_marginTop="30dp"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="EditText 1"

            />

        <EditText
            android:layout_marginTop="30dp"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="EditText 2"
            />

        <EditText
            android:layout_marginTop="30dp"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="EditText 3"
            />

        <EditText
            android:layout_marginTop="30dp"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="EditText 4"
            />

        <EditText

            android:hint="EditText 5"
            android:inputType="textNoSuggestions"
            />

        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:text="Button"
            />
        <TextView
            android:layout_width="wrap_content"

            android:text="any text"
        />
    </LinearLayout>
  </ScrollView>


</LinearLayout>

为所有editText、button和textview提供id:-

            <EditText
                android:layout_marginTop="30dp"

                android:hint="EditText 4"
                android:id="@+id/et4"/>

            <EditText
                android:layout_marginTop="30dp"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="EditText 5"
                android:inputType="textNoSuggestions"
                android:id="@+id/et5"/>

        </LinearLayout>

    </ScrollView>

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"

        android:id="@+id/tv"/>
</LinearLayout>

在您的清单中:-

android:windowSoftInputMode="adjustResize|stateHidden"

在你的Activity中:-

public class Main2Activity extends AppCompatActivity {
    EditText e1,e2,e3,e4,e5;
    Button button;
    TextView textView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);
        e1=(EditText)findViewById(R.id.et1);
        e2=(EditText)findViewById(R.id.et2);
        e3=(EditText)findViewById(R.id.et3);
        e4=(EditText)findViewById(R.id.et4);
        e5=(EditText)findViewById(R.id.et5);
        textView=(TextView)findViewById(R.id.tv);
        button=(Button)findViewById(R.id.btn);
        e1.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View view, boolean b) {
                hideKeyBoard();
            }
        });
        e2.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View view, boolean b) {
                hideKeyBoard();
            }
        });
        e3.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View view, boolean b) {
                hideKeyBoard();
            }
        });
        e4.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View view, boolean b) {
                hideKeyBoard();
            }
        });
        e5.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View view, boolean b) {
                hideKeyBoard();
            }
        });

    }
    private void hideKeyBoard(){
        final View activityRootView = findViewById(R.id.activity_main);
        activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                int heightDiff = activityRootView.getRootView().getHeight() - activityRootView.getHeight();
                if (heightDiff > dpToPx(Main2Activity.this, 200)) { // if more than 200 dp, it's probably a keyboard...
                    // ... do something here
                    button.setVisibility(View.GONE);
                    textView.setVisibility(View.GONE);
                }
                else {
                    button.setVisibility(View.VISIBLE);
                    textView.setVisibility(View.VISIBLE);
                }
            }
        });
    }
    public static float dpToPx(Context context, float valueInDp) {
        DisplayMetrics metrics = context.getResources().getDisplayMetrics();
        return TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, valueInDp, metrics);
    }

}

我在这里检查键盘是否可见。如果可见,则隐藏按钮和文本视图。

使用一个 Relavtive Layout 作为父级,将两个线性布局作为子级,并将滚动视图放在第一个线性布局中,而带有文本视图的按钮放在另一个中。

使用此代码。已测试,如您所愿。

            android:text="I don't want to push this TextView and Button above keyboard"
            />
    </LinearLayout>
</RelativeLayout>

首先更改布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:background="#ff0">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <EditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="30dp"
                android:hint="EditText 1"

                />

            <EditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="30dp"
                android:hint="EditText 2" />

            <EditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="30dp"
                android:hint="EditText 3" />

            <EditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="30dp"
                android:hint="EditText 4" />

            <EditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="30dp"
                android:hint="EditText 5"
                android:inputType="textNoSuggestions" />

        </LinearLayout>

    </ScrollView>


    <RelativeLayout
        android:id="@+id/rlBtm"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <Button
            android:id="@+id/btn"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Button" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/btn"
            android:text="I don't want to push this TextView and Button to above keyboard when keyboard is shown. Just obly want to push the ScrollView that contain all EditText"
            android:textColor="#000" />

    </RelativeLayout>

</LinearLayout>

然后添加 class

public class KeyboardUtil {

    public static void setKeyboardVisibilityListener(Activity activity, final KeyboardVisibilityListener keyboardVisibilityListener) {
        final View contentView = activity.findViewById(android.R.id.content);
        contentView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            private int mPreviousHeight;

            @Override
            public void onGlobalLayout() {
                int newHeight = contentView.getHeight();
                if (mPreviousHeight != 0) {
                    if (mPreviousHeight > newHeight) {
                        // Height decreased: keyboard was shown
                        keyboardVisibilityListener.onKeyboardVisibilityChanged(true);
                    } else if (mPreviousHeight < newHeight) {
                        // Height increased: keyboard was hidden
                        keyboardVisibilityListener.onKeyboardVisibilityChanged(false);
                    } else {
                        // No change
                    }
                }
                mPreviousHeight = newHeight;
            }
        });
    }
}

以及来自 onCreate 活动

KeyboardUtil.setKeyboardVisibilityListener(this, new KeyboardVisibilityListener() {
            @Override
            public void onKeyboardVisibilityChanged(boolean keyboardVisible) {
                rlBtm.setVisibility(keyboardVisible ? View.GONE : View.VISIBLE);
            }
        });

查找 rlBtm 的 ID。

  1. 已在所有 Nexus 移动设备和平板设备上进行测试。它工作正常。我正在使用您的布局 xml 代码,并且只向视图添加了 ID。

  2. 我在生产应用程序中使用以下库,它非常有前途。为达到同样的效果,请在 app gradle 中添加以下行: 'net.yslibrary.keyboardvisibilityevent:keyboardvisibilityevent:2.0.1' Here is the link for the same.

  3. 其余代码请参考以下要点:Manifest code, Activity code, Activity layout code

根据我的经验,上述解决方案可能在 20% 的时间内不起作用。对于一些三星设备,上面的代码没有按预期工作。如果我有时间会尝试使用 Constraintlayout 和 adjustPan 来解决它。

您可以使用下面的代码(但在这种情况下,您的按钮和文本视图位于屏幕的末端。否则您也可以使用线性布局来管理它。如果您想要按钮和文本视图必须显示,请询问。

借助 WindowInsetsCompat 的新功能,可以轻松检测键盘可见性(我按照此处的回答 )。
现在我可以通过将 windowSoftInputMode=adjustResizeWindowInsetsCompat

结合使用来解决这个问题,而不是像以前那样使用 windowSoftInputMode=adjustPan 来解决不那么复杂的问题
ViewCompat.setOnApplyWindowInsetsListener(root) { v, insets ->
    val isKeyboardVisible = insets.isVisible(WindowInsetsCompat.Type.ime())
    
    if (isKeyboardVisible) {
        // Hide some view when keyboard visible
    } else {
        // Show it again here
    }
}

AndroidManifest

<activity android:name=".activity_name"
        android:windowSoftInputMode="adjustResize"> // all content will push to above keyboard then we able to scroll to see whole content
   
</activity>
