Question

我的项目有问题。我想将裁剪的图像传递给其他活动。我已经完成了我的裁剪方法，但我无法获得它的真实路径。我之前已经搜索了如何获得路径，但我找到的所有方法都没有用。它总是给我零路径。所以，如果你们可以帮助我，请回答我的问题.. 这是我的代码

   public class MainActivity extends AppCompatActivity {
    Button btn;
    ImageView imgView;
    private Uri mImageCaptureUri;
    String realPath;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn = (Button) findViewById(R.id.button);
        imgView = (ImageView) findViewById(R.id.imageView);

        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                i.putExtra("crop","true");
                i.putExtra("aspectX", 1);
                i.putExtra("aspectY", 1);
                i.putExtra("outputX", 200);
                i.putExtra("outputY", 200);
                i.putExtra("return-data", true);
                startActivityForResult(i,2);

            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == 2 && resultCode == RESULT_OK && data != null){
            Uri uri = data.getData();
            String type = data.getType();
            Log.i("TAG", "Pick completed: " + uri + " " + type);
            if (uri != null)
            {
                String path = uri.toString();
                if (path.toLowerCase().startsWith("file://"))
                {
                    // Selected file/directory path is below
                    path = (new File(URI.create(path))).getAbsolutePath();
                    Log.e("ini", path);
                }

            }

            Bundle extras = data.getExtras();
            Bitmap img = extras.getParcelable("data");
            imgView.setImageBitmap(img);
        }


    }

如果我得到了真正的路径，我可以使用intent传递路径并将其应用于下一个imageview。我需要的只是路径。感谢

数据extraBundle中存在源URI。

Bundle extras = data.getExtras();
Bitmap img = extras.getParcelable("data");
imgView.setImageBitmap(img);

Uri selectedImageUri = Uri.parse(extras.get("src_uri").toString());
String realPath = getRealPathFromURI(selectedImageUri);


public String getRealPathFromURI(Uri uri) {

    String[] projection = { MediaStore.Images.Media.DATA };

    @SuppressWarnings("deprecation")
    Cursor cursor = managedQuery(uri, projection, null, null, null);

    int column_index = cursor
            .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);

    cursor.moveToFirst();
    return cursor.getString(column_index);
}

如何在裁剪后从SD卡获取真实路径图像？
