Why is android:FLAG_BLUR_BEHIND creating a gradient background in my new activity instead of bluring
- by nderraugh
Hi,
I've got two activities. One is supposed to be a blur in front of the other.
The background activity has several ImageViews which are set up as thin gradients extending across most of the screen and 10dip high. When I start the second activity it sets the background as a gradient occupying the entire window space, that is it appears to be fill_parent'd for both height and width. If I comment out the ImageViews then it blurs and looks as expected.
Any thoughts?
Here's the code doing the blur.
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.WindowManager;
import android.view.View.OnClickListener;
public class TransluscentBlurSummaryB extends Activity {
@Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND,
WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
getWindow().getAttributes().dimAmount = 0.5f;
getWindow().setFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND,
WindowManager.LayoutParams.FLAG_DIM_BEHIND);
setContentView(R.layout.sheetbdetails);
OnClickListener clickListener = new OnClickListener() {
public void onClick(View v) {
TransluscentBlurSummaryB.this.finish();
}
};
findViewById(R.id.sheetbdetailstable).setOnClickListener(clickListener);
}
}
And here's the layout with the ImageView gradients.

The gradient drawable is this.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<gradient
android:startColor="#FFFFFF" android:centerColor="#000000" android:endColor="#FFFFFF"
android:angle="270"/>
<padding android:left="7dp" android:top="7dp"
android:right="7dp" android:bottom="7dp" />
<corners android:radius="8dp" />
</shape>
And here's the layout from the activity doing the blurring on top.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/sheetbdetails"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true" >
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="vertical"
android:shrinkColumns="0"
android:id="@+id/sheetbdetailstable" >
<TableRow>
<TextView
android:padding="3dip" />
<TextView
android:text="You"
android:padding="3dip" />
<TextView
android:text="@string/otherparent"
android:padding="3dip" />
<TextView
android:text="Combined"
android:padding="3dip" />
</TableRow>
</TableLayout>
</ScrollView>
The transparent windows are themed from styles.xml in the apidemos using @style/Theme.Transparent.
