在你的onActivityResult中

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

        if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {

            Uri uri = data.getData();


            realPath = ImageFilePath.getPath(SignupActivity.this, data.getData());
//                realPath = RealPathUtil.getRealPathFromURI_API19(this, data.getData());

            Log.i(TAG, "onActivityResult: file path : " + realPath);
            try {
                Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
                // Log.d(TAG, String.valueOf(bitmap));

                ImageView imageView = (ImageView) findViewById(R.id.img_profile);
                imageView.setImageBitmap(bitmap);
                imageView.setVisibility(View.VISIBLE);

            } catch (IOException e) {
                e.printStackTrace();
            }
        } else {
            Toast.makeText(this, "Something Went Wrong", Toast.LENGTH_SHORT).show();
        }

    }

使用下面的代码,

public void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (resultCode == RESULT_OK) {

     Uri selectedImageUri = data.getData();
     String s = getRealPathFromURI(selectedImageUri);
     editText1.setText(s);
}
}

以下是你的getRealPathFromURI函数,

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);
}

派对有点晚了,但这是我的代码,希望这会有所帮助.

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        Uri selectedImageUri = data.getData( );
        String picturePath = getPath( getActivity( ).getApplicationContext( ), selectedImageUri );
        Log.d("Picture Path", picturePath);
    }
}

public static String getPath( Context context, Uri uri ) {
    String result = null;
    String[] proj = { MediaStore.Images.Media.DATA };
    Cursor cursor = context.getContentResolver( ).query( uri, proj, null, null, null );
    if(cursor != null){
        if ( cursor.moveToFirst( ) ) {
            int column_index = cursor.getColumnIndexOrThrow( proj[0] );
            result = cursor.getString( column_index );
        }
        cursor.close( );
    }
    if(result == null) {
        result = "Not found";
    }
    return result;
}
