我在谈到屏幕左边或右边时,想改变我的形象(我从一个网络中获取)。 我尝试使用TonListener,但我对发送TouchEvent有错误。
Using a gallery view is not the solution because I want the images displayed in full screen.
这是我使用的法典。
public class Prova4Activity extends Activity implements OnTouchListener {
/** Called when the activity is first created. */
ImageView image;
Bitmap trash = loadImageFromUrl("http://www.televideo.rai.it/televideo/pub/tt4web/Nazionale/16_9_page-100.6.png");
ImageView imgpag;
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.EDGE_RIGHT){
trash.recycle();
trash = null;
trash = loadImageFromUrl("http://www.televideo.rai.it/televideo/pub/tt4web/Nazionale/16_9_page-100.6.png");
image.setImageBitmap(trash);
}else if(event.getAction() == MotionEvent.EDGE_LEFT){
trash.recycle();
trash = null;
trash = loadImageFromUrl("http://www.televideo.rai.it/televideo/pub/tt4web/Nazionale/16_9_page-100.5.png");
imgpag.setImageBitmap(trash);
}
imgpag.setScaleType(ScaleType.FIT_XY);
return false;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
imgpag = (ImageView)findViewById (R.id.imgpag);
imgpag.setImageBitmap(trash);
imgpag.setOnTouchListener(this);
}
}
在日志中,我多次看到以下信息:
