ImageView转Bitmap
Bitmap bitmap = ((BitmapDrawable)img.getDrawable()).getBitmap();
Bitmap bitmap = ((BitmapDrawable)img.getDrawable()).getBitmap();
@Override public boolean onLongClick(View v) { if(v.getId()==R.id.listener_imageView1){ //长摁设置桌面背景 //1.清楚已有做面 try { ListenerDemoActivity.this.clearWallpaper(); // ListenerDemoActivity.this.setWallpaper(getApplicationContext().getResources().openRawResource(R.drawable.pic1)); textView2.setText("设置手机桌面背景成功!"); Bitmap bitmap = ((BitmapDrawable)img.getDrawable()).getBitmap(); ListenerDemoActivity.this.setWallpaper(bitmap); } catch (IOException e) { textView2.setText("设置手机桌面背景失败!!"); e.printStackTrace(); } } return false; } }
ImageView和Bitmap的转换,实例:设置当前查看图片为桌面背景
