Handling of click through non penetration in android transparent layout

Keywords: Android Java

;

Today's project requires that when webview is loading, a layer will pop up, showing that it is loading, and the background is transparent. Then it meets that when the layer pops up, the back can still click, so android:clickable = "true" is set in the middle

 <RelativeLayout
        android:id="@+id/relativeLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#55000000"
        android:clickable="true"
        android:visibility="visible">


        <RelativeLayout
            android:layout_width="360dp"
            android:layout_height="80dp"
            android:layout_centerInParent="true"
            android:background="@drawable/shape_10">
            <LinearLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerInParent="true"
                android:gravity="center_vertical"
                android:orientation="horizontal">
                <View
                    android:layout_width="40dp"
                    android:layout_height="40dp"
                    android:layout_centerVertical="true"
                    android:layout_marginLeft="20dp"
                    android:background="@drawable/loadingtianshi" />
                <TextView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_marginLeft="26dp"
                    android:clickable="false"
                    android:gravity="center_vertical"
                    android:text="Loading, please wait"
                    android:textSize="18sp" />
            </LinearLayout>
        </RelativeLayout>

However, strange things happened. When clicking, click monitoring really can't penetrate, but TextView's real "loading, please wait..." But it disappeared when clicking. Finally, the layer was changed in java

   //Prevent click through problems
        relativeLayout.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                return true;
            }
        });

To prevent textview messages from missing when clicking:

Key treatment:
Layer Android: layout? Centerinparent = "true"
Set the touch monitor of the layer, that is, consume the click
relativeLayout.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
return true;
}
});
