试试这个:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="@+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/holo_blue_dark"
android:text="TextView1" />
<TextView
android:id="@+id/textView3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/holo_green_dark"
android:text="TextView2"/>
</LinearLayout>
以编程方式将第一个视图的minHeight设置为。
ViewTreeObserver observer = linearLayout.getViewTreeObserver();
observer.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
int height = linearLayout.getHeight(); // set height/2 as minHeight for the first view
linearLayout.getViewTreeObserver().removeGlobalOnLayoutListener(this);
}
});
给出这个结果:
希望这对你有帮助:)
