我在RelativeLayout
内有一个relativeLayout和三个视图。视图彼此相对。
<RelativeLayout
android:id="@+id/includelayoutgroup"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/transparentColorView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:clickable="true"
android:visibility="visible" />
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/keyboard_main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:visibility="visible">
<include
layout="@layout/transfer_keyboard_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/finalRequestView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:clickable="true"
android:visibility="visible">
<include
layout="@layout/fragment_transfer_new_version_container_child"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
</RelativeLayout>
是否可以反转我的观点?我的意思是,在我的代码中,最后一个布局是finalRequestView
,在按钮单击中,我会在第一个位置看到我的上一个视图,在我的视图中看到其他视图的位置,
我怎么能解决这个问题?
答案 0 :(得分:0)
我尝试按照demo&amp; amp;它可以按你的需要工作,请看看
ReverseLayout.java
public class ReverseLayout extends AppCompatActivity {
LinearLayout llRoot;
Button btReverseLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.reverse_layout);
llRoot = (LinearLayout) findViewById(R.id.llRoot);
btReverseLayout = (Button) findViewById(R.id.btReverseLayout);
btReverseLayout.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
ArrayList<View> alViews = new ArrayList<View>();
for (int i = llRoot.getChildCount() - 1; i >= 0; i--) {
View view = llRoot.getChildAt(i);
llRoot.removeViewAt(i);
alViews.add(view);
}
for (int j = 0; j < alViews.size(); j++) {
llRoot.addView(alViews.get(j));
}
}
});
}
}
