Question

我正在尝试通过使用位于屏幕右上方的交叉图像（代码中的cancel_video_image_view）来关闭视图，如图像demo image中所示。它是第一次工作，但第二次无法工作，为什么设置点击监听器在运行线程内第二次不工作？请帮助： demo image 这是代码

@Override 
public void onTargetRecognized(final Tracker tracker_, final String targetName_) {
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            if (targetName_.toString().equalsIgnoreCase("TargetOne")) {
                LayoutInflater inflater = LayoutInflater.from(getApplicationContext());
                LinearLayout controls = (LinearLayout) inflater.inflate(R.layout.one_video_gallery, null);
                viewHolder.addView(controls);
                info_one_video_gallery = (TextView)findViewById(R.id.info_one_video_gallery);
                monument_name_one_video_gallery = (TextView)findViewById(R.id.monument_name_one_video_gallery);
                one_video_gallary_imageview = (ImageView)findViewById(R.id.one_video_gallary_imageview);
                one_video_gallary_thumbnail = (ImageView)findViewById(R.id.one_video_gallary_thumbnail);
                final ImageView cancel_video_image_view= (ImageView)findViewById(R.id.cancel_video_image_view);
                cancel_video_image_view.setClickable(true);


                one_video_gallary_imageview.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Intent intent = new Intent(getApplication(),MediaFullScreenImageActivity.class);
                        String monument_images = PropertyFile.TargetOne + "_images";
                        intent.putExtra("monument_images",monument_images);
                        startActivity(intent);
                    }
                });

                one_video_gallary_thumbnail.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Intent intent = new Intent(getApplicationContext(), MediaVideoActivity.class);
                        String monument = PropertyFile.TargetOne;
                        intent.putExtra("monument", monument);
                        String monument_images = PropertyFile.TargetOne + "_images";
                        intent.putExtra("monument_images", monument_images);
                        startActivity(intent);

                    }
                });


                if(cancel_video_image_view.getVisibility() == View.INVISIBLE){
                    cancel_video_image_view.setVisibility(View.VISIBLE);
                    cancel_video_image_view.setClickable(true);
                    one_video_gallary_imageview.setVisibility(View.VISIBLE);
                    one_video_gallary_thumbnail.setVisibility(View.VISIBLE);
                    info_one_video_gallery.setVisibility(View.VISIBLE);
                    monument_name_one_video_gallery.setVisibility(View.VISIBLE);

                }

                cancel_video_image_view.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Toast.makeText(getApplicationContext(), "You clicked the button", Toast.LENGTH_SHORT).show();
                        one_video_gallary_imageview.setVisibility(View.INVISIBLE);
                        one_video_gallary_thumbnail.setVisibility(View.INVISIBLE);
                        cancel_video_image_view.setVisibility(View.INVISIBLE);
                        info_one_video_gallery.setVisibility(View.INVISIBLE);
                        monument_name_one_video_gallery.setVisibility(View.INVISIBLE);


                    }
                });

     }

我认为你不应该在runOnUiThread中放置onClickListener。因为当调用onTargetRecongnized时，它只会在短时间内检查语句是否只是完成了runnable。

setonclicklistener在运行的线程
