我有imageView.我使用平底锅,捏捏imageView.有时我需要删除imageView.所以,我使用OnLongClickListener删除图像.当我使用长按我的imageView删除.但是,当我使用OnTouchListener进行平移时,会激活imageView OnLongPress并从视图中删除我的imageView.怎么解决这个？

码:

    imageView.setOnLongClickListener(new OnLongClickListener(){

     @Override
     public boolean onLongClick(View v) {
        // TODO Auto-generated method stub
                                    imageView.setVisibility(View.GONE);

      return true;
        }

  });



   imageView.setOnTouchListener(new View.OnTouchListener() {
       final Handler handler = new Handler(); 
    Runnable mLongPressed = new Runnable() { 
        public void run() { 
            Log.i("", "Long press!");
        }   
    };



     @Override
       public boolean onTouch(View v,MotionEvent event) {
        // TODO Auto-generated method stub

    if(event.getAction() == MotionEvent.ACTION_DOWN)
        handler.postDelayed(mLongPressed, 1000);
    if((event.getAction() == MotionEvent.ACTION_MOVE)||(event.getAction() ==     MotionEvent.ACTION_UP))
        handler.removeCallbacks(mLongPressed);



    layoutParams = (RelativeLayout.LayoutParams) imageView.getLayoutParams();

        switch(event.getAction())
         {
     case MotionEvent.ACTION_DOWN :
      {
          parms = …

我有一个ImageView.我需要onLongClickListener用于ImageView.当我使用这段代码时,没有任何事

码:

 gallery=(Gallery)findViewById(R.id.gall1);

 gallery.setAdapter(new ImageAdapter(MainActivity.this));

            gallery.setOnItemClickListener(new OnItemClickListener()
            {

                @Override
                public void onItemClick(
                        AdapterView<?> parent, View v,
                        int position, long id) {
                    // TODO Auto-generated method stub

                    final ImageView imageView = (ImageView) findViewById(R.id.image1);
                    imageView.setImageResource(imageIDs[position]);

                    imageView.setLongClickable(true);


     imageView.setOnLongClickListener(new View.OnLongClickListener(){

        @Override
        public boolean onLongClick(View v) {
            // TODO Auto-generated method stub

                            Toast.makeText(getApplicationContext(), "Long Press work", Toast.LENGTH_SHORT).show();

        return true;
            }

      });


  imageView.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public boolean onTouch(View v,MotionEvent event) {
    // TODO Auto-generated method stub
    layoutParams = (RelativeLayout.LayoutParams) imageView.getLayoutParams();

        switch(event.getAction()) …

我使用AVCaptureSession拍照并将照片存储到相册.当我点击按钮时,它会拍摄快照并存储到相册.但是当我使用横向模式时,然后单击它存储横向模式的按钮会导致倒置静止图像.

码:

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    [self setCaptureSession:[[AVCaptureSession alloc] init]];


    [self  addVideoInputFrontCamera:NO]; // set to YES for Front Camera, No for Back camera

    [self  addStillImageOutput];

    [self setPreviewLayer:[[AVCaptureVideoPreviewLayer alloc] initWithSession:[self captureSession]] ];

      [[self previewLayer] setVideoGravity:AVLayerVideoGravityResizeAspectFill];

      CGRect layerRect = [[[self view] layer] bounds];


    [[self previewLayer]setBounds:layerRect];
    [[self  previewLayer] setPosition:CGPointMake(CGRectGetMidX(layerRect),CGRectGetMidY(layerRect))];
    [[[self view] layer] addSublayer:[self  previewLayer]];

     [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(saveImageToPhotoAlbum) name:kImageCapturedSuccessfully object:nil];


    [[self captureSession] startRunning];

camera=[UIButton buttonWithType:UIButtonTypeCustom];
[camera setImage:[UIImage imageNamed:@"button.png"] forState:UIControlStateNormal];
[camera setFrame:CGRectMake(150, 10, 40, …
