android – 我可以将控件组合在一起吗？

使用LinearLayout(或其他ViewGroup,如relativeLayout)并将TextView(和其他组件)放入其中：

<LinearLayout xmlns:android="http://scheR_763_11845@as.android.com/apk/res/android"
    android:id="@+id/container"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:visibility="visible">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"        
        android:textAppearance="?android:attr/textAppearancesmall" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"      
        android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>

从代码

LinearLayout container = (LinearLayout) findViewById(R.id.container);
container.setVisibility(View.VISIBLE); //to show it

要么

container.setVisibility(View.GONE); //to hide it
