我希望你能幫我解決我的簡單問題。我試圖從我的畫廊中選擇要在我的Imageview上顯示的圖像,但它可以正常工作,但在關閉我的應用程序後它會消失。請檢查我在下面找到的代碼。從應用關閉後,從圖庫中選擇的圖像從Imageview中消失
iv=(ImageView) rootView.findViewById(R.id.profpic);
iv.setOnClickListener(this);
private void showFileChooser() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
try {
startActivityForResult(
Intent.createChooser(intent, "Select a File to Upload"),
FILE_SELECT_CODE);
} catch (android.content.ActivityNotFoundException ex) {
// Potentially direct the user to the Market with a Dialog
Toast.makeText(getActivity(), "Please install a File Manager.",
Toast.LENGTH_SHORT).show();
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case FILE_SELECT_CODE:
if (resultCode == Activity.RESULT_OK) {
// Get the Uri of the selected file
Uri uri = data.getData();
iv.setImageURI(uri);
Log.d(TAG, "File Uri: " + uri.toString());
}
break;
}
super.onActivityResult(requestCode, resultCode, data);
}
和我的XML:
<ImageView
android:id="@+id/profpic"
android:layout_width="113dp"
android:layout_height="113dp"
android:paddingRight="1dp"
android:src="@drawable/propic" />
我是新android開發任何幫助將不勝感激。提前致謝!
