我已经使用viewFlipper. 现在我想setWallpaper。但是当我按下setWallpaper按钮时，我的 coad 不工作。这是我的代码：
public class WallpaperChooserActivity extends Activity implements OnClickListener {
/** Called when the activity is first created. */
ViewFlipper vp;
Bitmap bmp;
ImageView image;
int i;
int galleryId [] ={R.drawable.bela1,R.drawable.bela2,R.drawable.bela3,
R.drawable.bela4,R.drawable.bela5};
private void setFlipperImage1(int res) {
// Log.i("Set Filpper Called", res+"");
image = new ImageView(getApplicationContext());
image.setImageResource(res);
vp.addView(image);
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initilizeVariable();
for(int i=0;i<galleryId.length;i++)
{
setFlipperImage1(galleryId[i]);
}
}
private void initilizeVariable() {
// TODO Auto-generated method stub
vp =(ViewFlipper)findViewById(R.id.ViewFlipper01);
Button setWall = (Button)findViewById(R.id.btnSetWall);
Button moreApp = (Button) findViewById(R.id.btnMore);
Button share = (Button) findViewById(R.id.btnShare);
Button rate = (Button)findViewById(R.id.btnRate);
ImageButton next = (ImageButton)findViewById(R.id.ibNext);
ImageButton prev = (ImageButton)findViewById(R.id.ibPrev);
setWall.setOnClickListener(this);
moreApp.setOnClickListener(this);
share.setOnClickListener(this);
rate.setOnClickListener(this);
next.setOnClickListener(this);
prev.setOnClickListener(this);
}
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()){
case R.id.ibNext:
vp.showNext();
break;
case R.id.ibPrev:
vp.showPrevious();
break;
case R.id.btnSetWall:
//Bitmap wallpaper = BitmapFactory.decodeStream(getResources().openRawResource(galleryId [i]));
WallpaperManager myWallpaperManager = WallpaperManager.getInstance(getApplicationContext());
try {
myWallpaperManager.setResource(galleryId [i]);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}break;
}
}
}
