无法在Android中从图像库将图像设置为imageview

Question

@Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode != Activity.RESULT_CANCELED) {
      if (requestCode == PICK_IMAGE) {
        Uri selectedImageUri = data.getData();
        Log.d("PICK_IMAGE", selectedImageUri.toString());
        Dialog settingsDialog = new Dialog(this);
        settingsDialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        settingsDialog.setContentView(getLayoutInflater().inflate(R.layout.custom_dailogue, null));
        img_in_dailogue = (ImageView) findViewById(R.id.img_in_dailogue);
        ImageView img_in_dailogue = new ImageView(this);
        LinearLayout.LayoutParams vp = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
        img_in_dailogue.setLayoutParams(vp);
        img_in_dailogue.setMaxHeight(250);
        img_in_dailogue.setMaxWidth(350);
        img_in_dailogue.setImageURI(Uri.parse(selectedImageUri.toString()));
        settingsDialog.show();
      }
    }
  }

null

img_in_dailogue.setImageURI(Uri.parse(selectedImageUri.toString()));

那个代码有什么问题？我不明白为什么不能将ImageRi发送到ImageView。我还验证了我正在传递给setImageURI函数的Uri值是正确的。

Answer 1

img_in_dailogue = (ImageView) findViewById(R.id.img_in_dailogue);
ImageView img_in_dailogue = new ImageView(this);

ImageView img_in_dailogue = new ImageView(this);
img_in_dailogue = (ImageView) findViewById(R.id.img_in_dailogue);
