如何隐藏和显示多个布局?

How to hide and show multiple layouts?

我有 3 个可见性设置为 GONE 的相关布局和 3 个按钮。我希望当我按下一个按钮显示一个特定的布局时,当我按下另一个按钮显示一个不同的布局并隐藏以前的布局时。

这是我的 activity xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">


<Button
    android:id="@+id/btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="12dp"

<RelativeLayout
    android:id="@+id/rel"
    android:visibility="gone"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <TextView
        android:id="@+id/text1"
        android:text="Text 1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</RelativeLayout>
<Button
    android:id="@+id/btn2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="12dp"
<RelativeLayout
    android:id="@+id/rel2"
    android:visibility="gone"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <TextView
        android:id="@+id/text2"
        android:text="Text 2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</RelativeLayout>

<Button
    android:id="@+id/btn3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="12dp"
<RelativeLayout
    android:id="@+id/rel3"
    android:visibility="gone"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <TextView
        android:id="@+id/text3"
        android:text="Text 3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
</RelativeLayout>

我已经按照你的格式格式化了代码,试试这个:

RelativeLayout layout1,layout2,layout3;
        Button button1,button2,button3;

        @Override
            protected void onCreate(Bundle savedInstanceState) {
                // TODO Auto-generated method stub
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_main);
                layout1=(RelativeLayout) findViewById(R.id.rel);
                layout2=(RelativeLayout) findViewById(R.id.rel2);
                layout3=(RelativeLayout) findViewById(R.id.rel3);
                button1=(Button) findViewById(R.id.btn);
                button2=(Button) findViewById(R.id.btn2);
                button3=(Button) findViewById(R.id.btn3);
            button1.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                layout1.setVisibility(View.VISIBLE);
                layout2.setVisibility(View.GONE);
                layout3.setVisibility(View.GONE);
              }
            });
    button2.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                layout1.setVisibility(View.GONE);
                layout2.setVisibility(View.VISIBLE);
                layout3.setVisibility(View.GONE);
              }
            });
    button3.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                layout1.setVisibility(View.GONE);
                layout2.setVisibility(View.GONE);
                layout3.setVisibility(View.VISIBLE);
              }
            });
        }
