Question

@Override
protected void onCreate(Bundle savedInstanceState) {      
    super.onCreate(savedInstanceState);
    setContentView(R.layout.picture_choice_activity);

    Button takePictureButton = (Button)findViewById(R.id.takePictureButton);
    takePictureButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v){
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(intent, IMAGE_CAPTURE);
        }
    });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(requestCode == IMAGE_CAPTURE){
        if(resultCode == Activity.RESULT_OK){
            // I should get the path here
        }else if(resultCode == Activity.RESULT_CANCELED){

        }
    }
}

在上述法典中,我试图找到被抓住的形象。我不应利用EXTRA_OUTPUT来说明挽救形象的习俗途径。我如何能够这样做?

MediaStore.EXTRA_OUTPUT: 这种环境要求Uri物体在你想要挽救照片的地方注明道路和档案名称。这一背景是任择性的,但强烈建议。如果你没有具体说明这一价值,照相申请就可节省在默认地点使用的照片,并注明返回意向书的现场。

在活动结果中使用

final Uri contentUri = data.getData();
final String[] proj = { MediaStore.Images.Media.DATA};
final Cursor cursor = managedQuery(contentUri, proj, null, null, null);
final int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToLast();
final String path = cursor.getString(column_index);
