在此先感谢

推荐答案

第一部分和两个应该是在自己的布局。之后，玩每个布局的 visilibity 属性。具体要隐藏任何视图没有它仍然占据它的空间，使用值消失的可见性属性。

Part one and two should be in their own layout. After, play with the visilibity property of each layout. Specifically to hide any view without it continues to occupy its space, use the value gone for the visibility property.

好了，在这里我走了。下面你有如何隐藏一个完整的例子/显示分组的看法。

Ok, here I go. Below you have a complete example of how to hide/show grouped views.

的main.xml

<RelativeLayout 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" >

    <LinearLayout
        android:id="@+id/viewsContainer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:padding="5dp" >

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="TextBox One" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:text="TextBox Two" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:text="TextBox Three" />
    </LinearLayout>

    <Button
        android:id="@+id/button"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:text="Hide" />

</RelativeLayout>

活动

public class MyActivity extends Activity implements OnClickListener {

    private boolean viewGroupIsVisible = true;  

    private View mViewGroup;
    private Button mButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mViewGroup = findViewById(R.id.viewsContainer);

        mButton = findViewById(R.id.button);
        mButton.setOnClickListener(this);
    }


    @Override
    public void onClick(View button) {

    if (viewGroupIsVisible) {
        mViewGroup.setVisibility(View.GONE);
        mButton.setText("Show");
    } else {
        mViewGroup.setVisibility(View.VISIBLE);
        mButton.setText("Hide");
    }

    viewGroupIsVisible = !viewGroupIsVisible;
}

我希望这有助于;）

I hope this helps ;)
