onTouchListener不工作

Question

CODE：

public class ImageActivity extends FragmentActivity { 

    ImageView mClickedImage; 
    PhotoViewAttacher mPhotoViewAttacher; 
    TextView mRotate_imageActivity; 
    private int BASEINT_ImageActivity; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_image); 
     Intent intent = getIntent(); 
     final String string = (String) intent.getSerializableExtra("Clicked Image"); 
     mClickedImage = (ImageView) findViewById(R.id.iv_clicked_image); 
     mRotate_imageActivity = (TextView) findViewById(R.id.tv_rotate_imageActivity); 

     mPhotoViewAttacher = new PhotoViewAttacher(mClickedImage); 

     Glide.with(getApplicationContext()) 
       .load(string) 
       .fitCenter() 
       .into(mClickedImage); 

     mRotate_imageActivity.setOnTouchListener(new View.OnTouchListener() { 
      @Override 
      public boolean onTouch(View view, MotionEvent motionEvent) { 
        Glide.with(getApplicationContext()) 
          .load(string) 
          .diskCacheStrategy(DiskCacheStrategy.ALL) 
          .transform(new RotateHelper(getApplicationContext(), 90f)) 
          .into(mClickedImage); 

       return true; 
      } 
     }); 
    } 
} 

XML代碼：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/activity_image" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.keepair.www.pinair.ImageActivity"> 

    <RelativeLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:id="@+id/rl_rotate_text"> 

     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:id="@+id/tv_rotate_imageActivity" 
      android:text="@string/rotate"/> 
    </RelativeLayout> 

    <ImageView 
     android:layout_centerInParent="true" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:id="@+id/iv_clicked_image"/> 
</RelativeLayout> 

正如你可以在上面看到，我的XML代碼說的TextView是ImageView的。他們被重疊。

但我認爲，因爲photoviewattacher，onTouchListener爲TextView寫了什麼，mRotate_imageActivity不起作用。

問題：我該如何讓onTouchListener工作？

Answer 1

你需要改變的是ImageView

// If you later call mImageView.setImageDrawable/setImageBitmap/setImageResource/etc then you just need to call 
mAttacher.update(); 

像你的情況後打電話到update在PhotoViewAttacher，您可以附加一個偵聽滑翔知道得到了加載圖像時，更新PhotoViewAttacher那裏。

Glide.with(getActivity()) 
    .load(args.getString(IMAGE_TO_SHOW)) 
    .listener(new RequestListener<String, GlideDrawable>() { 
     @Override 
     public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) { 
      return false; 
     } 

     @Override 
     public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) { 
      mAttacher.update(); 
      return false; 
     } 
    }) 
    .into(imageView)
