如何使相機應用程序中的自定義圖像查看

Question

上午工作在android自定義相機應用程序應用程序正在工作，但我有一個問題，當我捕捉它保存的圖像，當我點擊保存的圖像它打開手機默認視圖，但我想擁有自定義圖像視圖中，我可以刷卡左，右刪除和分享怎麼可能

enter code here 
    public void clickedGallery(View view) { 
    if (MyDebug.LOG) 
     Log.d(TAG, "clickedGallery"); 
    //Intent intent = new Intent(Intent.ACTION_VIEW, MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
    Uri uri = null; 
    Media media = getLatestMedia(); 
    if (media != null) { 
     uri = media.uri; 
    } 

    if (uri != null) { 
     // check uri exists 
     if (MyDebug.LOG) 
      Log.d(TAG, "found most recent uri: " + uri); 
     try { 
      ContentResolver cr = getContentResolver(); 
      ParcelFileDescriptor pfd = cr.openFileDescriptor(uri, "r"); 
      if (pfd == null) { 
       if (MyDebug.LOG) 
        Log.d(TAG, "uri no longer exists (1): " + uri); 
       uri = null; 
      } 
      pfd.close(); 
     } catch (IOException e) { 
      if (MyDebug.LOG) 
       Log.d(TAG, "uri no longer exists (2): " + uri); 
      uri = null; 
     } 
    } 
    if (uri == null) { 
     uri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI; 
    } 
    if (!is_test) { 
     // don't do if testing, as unclear how to exit activity to finish test (for testGallery()) 
     if (MyDebug.LOG) 
      Log.d(TAG, "launch uri:" + uri); 
     final String REVIEW_ACTION = "com.android.camera.action.REVIEW"; 
     try { 
      // REVIEW_ACTION means we can view video files without autoplaying 
      Intent intent = new Intent(REVIEW_ACTION, uri); 
      this.startActivity(intent); 
     } catch (ActivityNotFoundException e) { 
      if (MyDebug.LOG) 
       Log.d(TAG, "REVIEW_ACTION intent didn't work, try ACTION_VIEW"); 
      Intent intent = new Intent(Intent.ACTION_VIEW, uri); 
      // from http://stackoverflow.com/questions/11073832/no-activity-found-to-handle-intent - needed to fix crash if no gallery app installed 
      //Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("blah")); // test 
      if (intent.resolveActivity(getPackageManager()) != null) { 
       this.startActivity(intent); 
      } else { 
       preview.showToast(null, R.string.no_gallery_app); 
      } 
     } 
    } 
}

You can customize your image view add all functionality in the class like this i create a image view as a circle imageview. 


import android.content.Context; 
import android.graphics.Canvas; 
import android.graphics.Path; 
import android.graphics.RectF; 
import android.util.AttributeSet; 
import android.widget.ImageView; 

public class RoundedImageView extends ImageView { 

    public RoundedImageView(Context context) { 
     super(context); 

    } 

    public RoundedImageView(Context context, AttributeSet attrs) { 
     super(context, attrs); 

    } 

    public RoundedImageView(Context context, AttributeSet attrs, 
      int defStyle) { 

     super(context, attrs, defStyle); 
    } 

    @Override 
    protected void onDraw(Canvas canvas) { 
     float radius = 90.0f; // angle of round corners 
     Path clipPath = new Path(); 
     RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight()); 
     clipPath.addRoundRect(rect, radius, radius, Path.Direction.CW); 
     canvas.clipPath(clipPath); 

     super.onDraw(canvas); 

    } 
}
