我希望它是这样的。

editButton.setOnClickListener(new Button.OnClickListener(){

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent goEdit;
            goEdit = new Intent(PreviewActivity.this, CropImage.class);
            goEdit.putExtra("image-path", path);
            goEdit.putExtra("scale", true);
            goEdit.putExtra("fileName", nameFromPath);
            //finish();
            checkEdit = true;
            startActivityForResult(goEdit,0);

        }
});

修改 我用这个按钮，监听器调用的类CropImage活动来调用到cropImage文件。这是一个自定义的意图不是内的Andr​​oid作物功能，但我认为它的副本，以便让所有的版本都支持，但是当我打电话到其选定的区域心不是照亮我唐诺哪里出了问题，谁能指导我？谢谢 这是我使用的库<一href="https://github.com/chemalarrea/CropImage/tree/master/src/com/droid4you/util/cropimage">drioid4you裁剪图片

EDIT I use this button listener to call into the cropImage file by calling to the class CropImage activity. This is a custom intent not the crop feature inside android but I think is the copy of it so that make it support for all versions but when I call into it the selected area isnt brighten and I donno where is the problem can anyone guide me? Thanks This is the library I'm using drioid4you crop image

推荐答案

您可以使用默认的Andr​​oid裁切功能？

Can you use default android Crop functionality?

下面是我的code

private void performCrop(Uri picUri) {
    try {

        Intent cropIntent = new Intent("com.android.camera.action.CROP");
        // indicate image type and Uri
        cropIntent.setDataAndType(picUri, "image/*");
        // set crop properties
        cropIntent.putExtra("crop", "true");
        // indicate aspect of desired crop
        cropIntent.putExtra("aspectX", 1);
        cropIntent.putExtra("aspectY", 1);
        // indicate output X and Y
        cropIntent.putExtra("outputX", 128);
        cropIntent.putExtra("outputY", 128);
        // retrieve data on return
        cropIntent.putExtra("return-data", true);
        // start the activity - we handle returning in onActivityResult
        startActivityForResult(cropIntent, PIC_CROP);
    }
    // respond to users whose devices do not support the crop action
    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();
    }
}

申报：

final int PIC_CROP = 1;

在上面。

在onActivity结果的方法，下面令状code：

In onActivity result method, writ following code:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == PIC_CROP) {
        if (data != null) {
            // get the returned data
            Bundle extras = data.getExtras();
            // get the cropped bitmap
            Bitmap selectedBitmap = extras.getParcelable("data");

            imgView.setImageBitmap(selectedBitmap);
        }
    }

}

这是pretty的容易让我实现，也显示变暗的区域。

It is pretty easy for me to implement and also shows darken areas.
