通過android畫廊裁剪方法裁剪可拖動的圖像

Question

Onclick我的Imageview，我想裁剪我的應用程序的可繪製文件夾中的圖像視圖的背景圖像默認裁剪技術的Android圖庫和裁剪圖像應設置相同一旦它被裁剪。

@Override 
public void onClick(View v) { 
    // TODO Auto-generated method stub 
    final Intent intent = new Intent("com.android.camera.action.CROP"); 
    intent.setDataAndType(Uri.parse("android.resource://com.example.croppingactivity/drawable/apple"), "image/*"); 
    intent.putExtra("outputX", 400); 
    intent.putExtra("outputY", 400); 
    intent.putExtra("aspectX", 1); 
    intent.putExtra("aspectY", 1); 
    intent.putExtra("scale", true); 
    intent.putExtra("crop", true); 
    //intent.putExtra("output", Uri.parse("android.resource://com.example.croppingactivity/drawable/apple")); 
    startActivityForResult(intent, 1); 
} 

這是我的堆棧跟蹤。

但它不起作用。我沒有找到活動異常。 我做錯了，請幫助我。

嗯，這是我用來做這種事情的代碼。也許你可以試試：

final Intent intent = new Intent(); 
intent.setAction(Intent.ACTION_GET_CONTENT); 
intent.setType("image/*"); 

intent.putExtra("crop", "true"); 

intent.putExtra("aspectX", 1); 
intent.putExtra("aspectY", 1); 

intent.putExtra("outputX", 400); 
intent.putExtra("outputY", 400); 
// Scale the image down to 400 x 400 
intent.putExtra("scale", true); 

intent.putExtra("windowTitle", "My_title"); 
    // You need to use a temporary file for cropping to work 
    File tempFile = File.createTempFile("crop", "png", 
       myActivity.getCacheDir()); 
mSavedUri = Uri.fromFile(tempFile); 
intent.putExtra("output", mSavedUri); 
intent.putExtra("outputFormat", "PNG"); 

profileActivity.startActivityForResult(intent, INTENT_PICK_PICTURE); 

我想你必須改變intent.setType(...)到intent.setDataAndType(Uri.parse("android.resource://..."), "image/*")
