我曾尝试以下code。然而,它总是导致160 * 160尺寸的图像。
I have tried the below code. However, it always results the 160*160 dimension image.
try {
//call the standard crop action intent (the user device may not support it)
Intent cropIntent = new Intent("com.android.camera.action.CROP");
//indicate image type and Uri
cropIntent.setDataAndType(Uri.fromFile(pictureFile), "image/*");
//set crop properties
cropIntent.putExtra("crop", "true");
//indicate aspect of desired crop
cropIntent.putExtra("aspectX", 100);
cropIntent.putExtra("aspectY", 100);
cropIntent.putExtra("scale", true);
//indicate output X and Y
cropIntent.putExtra("outputX", 500);
cropIntent.putExtra("outputY", 500);
//retrieve data on return
cropIntent.putExtra("return-data", true);
//start the activity - we handle returning in onActivityResult
startActivityForResult(cropIntent, CROP_IMAGE);
} catch(ActivityNotFoundException anfe) {
//display an error message
String errorMessage = "Whoops - your device doesn't support the crop action!";
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
我想传递的路径,裁剪图像。 我并不想捕捉/选择从默认的摄像头应用程序或画廊。请帮我在这。
I would like to crop an image by passing its path. I don't want to capture/pick from default camera app or gallery. Please help me on this.

我已经解决了这个被创建调用意向,并把该文件的路径,通过意图存储裁剪后的图像前,一个新的文件。下面是这种情况的解决方案。
I have solved this by create a new file before calling Intent and passing this file path to store the cropped image through intent. Here is the solution for this.
private Uri mCropImagedUri;
/**Crop the image
* @return returns <tt>true</tt> if crop supports by the device,otherwise false*/
private boolean performCropImage(){
try {
if(mFinalImageUri!=null){
//call the standard crop action intent (the user device may not support it)
Intent cropIntent = new Intent("com.android.camera.action.CROP");
//indicate image type and Uri
cropIntent.setDataAndType(mFinalImageUri, "image/*");
//set crop properties
cropIntent.putExtra("crop", "true");
//indicate aspect of desired crop
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
cropIntent.putExtra("scale", true);
//indicate output X and Y
cropIntent.putExtra("outputX", 500);
cropIntent.putExtra("outputY", 500);
//retrieve data on return
cropIntent.putExtra("return-data", false);
File f = createNewFile("CROP_");
try {
f.createNewFile();
} catch (IOException ex) {
VLLog.e("io", ex.getMessage());
}
mCropImagedUri = Uri.fromFile(f);
cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, mCropImagedUri);
//start the activity - we handle returning in onActivityResult
startActivityForResult(cropIntent, CROP_IMAGE);
return true;
}
}
catch(ActivityNotFoundException anfe){
//display an error message
String errorMessage = "Whoops - your device doesn't support the crop action!";
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
return false;
}
return false;
}
private File createNewFile(String prefix){
if(prefix==null || "".equalsIgnoreCase(prefix)){
prefix="IMG_";
}
File newDirectory = new File(Environment.getExternalStorageDirectory()+"/mypics/");
if(!newDirectory.exists()){
if(newDirectory.mkdir()){
VLLog.d(mContext.getClass().getName(), newDirectory.getAbsolutePath()+" directory created");
}
}
File file = new File(newDirectory,(prefix+System.currentTimeMillis()+".jpg"));
if(file.exists()){
//this wont be executed
file.delete();
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
return file;
}
所以在这里,我们不应该理会它进来 onActivityResult数据()
方法。
