Question

We have foreground image where some area of that image are transparent & we are showing another image underlying in transparent region. So when we are going to save it, it will be saving full screen. so we want particular area of screen to be saved in the gallery. Here is the code which we used to save..

save.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mDecorView = getWindow().getDecorView();
runOnUiThread(new Runnable() {
public void run() {
mDecorView.invalidate();
mDecorView.post(this);
}
});
View v1 = mDecorView.getRootView();
System.out.println("Root View : "+v1);
v1.setDrawingCacheEnabled(true);

try {
BitmapSave(v1.getDrawingCache());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

});

Please help us friends. Thanks

你想修改你从屏幕上抽取的比照图,然后再加以挽救。

使用:

Bitmap bmp=v1.getDrawingCache()); 
int startX=0,startY=0,endX=30,endY=230;
Bitmap bitmap=Bitmap.createBitmap(bm, startX,startY, endX, endY); 
BitmapSave(bitmap);

改变开端和端Xy阵地,使屏幕能够协调你们想要节省的费用。
