Android "No view found for id for fragment"

Question

好的。我被卡住了并且头疼......我不确定如何访问其他布局的视图，因为膨胀不起作用。这是我的代码。

WriteRouteActivity.java

public class WriteRouteActivity extends AppCompatActivity {

    private Toolbar tb;
    private TextView txt_toolbar_title;
    private Button btnSearchPlaces;
    private LinearLayout parentLayout, placesCoverLayout;
    private View popupView;
    private ImageView imgShowPlaces;
    private boolean isKeyBoardVisible;
    private int keyboardHeight;
    private EditText edtSearchPlaces;

    //popupView
    private TabLayout tabLayout;
    private FrameLayout frameLayout;

    //prework
    private int minusVal;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_write_route);
        initView();

    }

    private void initView() {
        //for activity and native back button

        tb = (Toolbar) findViewById(R.id.nav_toolbar);
        setSupportActionBar(tb);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDisplayShowTitleEnabled(false);
        txt_toolbar_title = (TextView) findViewById(R.id.txt_toolbar);

        parentLayout = (LinearLayout) findViewById(R.id.layout_parent);
        placesCoverLayout = (LinearLayout) findViewById(R.id.footer_for_places);

FATAL EXCEPTION: main Process: suacuration.itgotravel, PID: 20131 java.lang.IllegalArgumentException: No view found for id 0x7f100173 for fragment Fragment_zasin{d4ac39c #0 id=0x7f100173 first}

有人可以帮忙吗？

Answer 1

可能还有其他错误，但这是什么？

tb = (Toolbar) findViewById(R.id.nav_toolbar);

这不是工具栏：

<include layout="@layout/nav_toolbar" />

我们能看到这个 nav_toolbar 布局的内部吗？

此外，这是哪里："R.layout.fragment_zasin"。它在抱怨一个片段，所以值得看看这是否可以。

无论如何，作为一般的故障排除策略，请尝试注释掉 initView() 方法中的所有这些行，然后一次只添加一个，直到它失败。或者，如果您进一步向下滚动错误日志，它会给您一个指向导致它失败的行的超链接。

为什么你的一行是 "frameLayout.getId()" 而另一行是 "R.id.frame_layout"？尝试对所有行使用后者，看看是不是这样。

Answer 2

发生此错误是因为片段管理器找不到它必须在其上扩充片段的视图。

片段事务链接到 activity，因此出现此错误是因为框架布局不是主 activity 的一部分 xml.so 它无法找到添加位置fragment.fragment 必须添加到 activity.

中

您需要做的是在主 activity 中提供视图的 ID。例如你的主视图

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_parent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/mainView"//like this
android:orientation="vertical">

<include layout="@layout/nav_toolbar" />

<fragment
    android:id="@+id/google_map"
    class="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" />


<include
    android:id="@+id/footer_layout"
    layout="@layout/footer_edittext"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

<LinearLayout
    android:id="@+id/footer_for_places"
    android:layout_width="match_parent"
    android:layout_height="@dimen/keyboard_height"
    android:background="@android:color/transparent"
    android:orientation="vertical"
    android:visibility="gone" />
 </LinearLayout>

您尝试膨胀碎片的视图必须在 activity 内。现在当你尝试

frManager.beginTransaction().add(R.id.mainView, ((Fragment) Fragment_zasin.class.newInstance()), tag).commit();

片段将加载到您 activity 的这个视图中。

Answer 3

问题是您正试图在 View 上显示 Fragment，而您在 onCreate() 中定义的布局中未定义 setContentView(layoutId)

在你的情况下，你在 WriteRouteActivity 中膨胀片段，其中布局定义为 activity_write_route，片段添加在 FrameLayout 上，FrameLayout 定义在 places_popup.xml 中，所以定义你的 framelayout 在 Activity 的视图布局中。

小说明：

--------code------
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
-------layout define for activity-------
setContentView(R.layout.activity_write_route);
}

现在您要在 FrameLayout(view)

上添加片段的位置

frManager.beginTransaction().add(R.id.frame_layout, ((Fragment) Fragment_zasin.class.newInstance()), tag).commit();

此处 R.id.frame_layout 应在您的布局中定义 activity_write_route。

Answer 4

您收到此错误是因为 您的视图在片段 Fragment_zasin 中找到了 ID 0x7f100173，所以唯一的解决方案是：

1) 检查该特定布局中存在的所有 ID。

2) 如果所有 id 都存在于该特定布局，但您仍然面临同样的问题，请做一件事更改 id 的名称不要重构更改名称并在您的片段中访问此更改的 id 名称或 activity .

Answer 5

好的，我找到了答案。问题是片段不能是 'Dialog' 的子片段。由于我使用了弹出对话框，因此无法将片段放入对话框中。

我通过膨胀视图而不是在 tablayout 中使用片段来解决。

Answer 6

我扩展了错误类型的 activity，扩展的 AppCompact 解决了问题。

Answer 7

在事务替换方法中使用 ChildFragmentManager 从片段开始新片段并从 activity 给出容器 ID 时出现此错误。碰巧 FragmentManager 可以访问 activity 容器，但 ChildFragmentManager 可以访问片段容器。解决方案是使用 FragmentManager class 而不是 ChildFragmentManager.
