[英]Android get the value null when passing from fragment to dialogfragment
我有一個問題,我使用包將數據從片段發送到dialogfragment,但是當我單擊片段布局中的按鈕時,成功從片段中獲取數據卻在我的dialogfragment中獲取空值是有問題的調試我發現我的對話框片段運行了兩次,所以為什么我得到了空值。 任何解決這個問題的建議,對不起我的英語,希望能理解我的問題。
這是我將數據傳遞到我的對話框片段的onclick
Button[i].setBackgroundColor(0xFF00FF00);
Button[i].setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
TextView test = (TextView)getView().findViewById(R.id.testproductname);
test.setText(pName);
String testproductname = test.getText().toString();
Bundle args = new Bundle();
args.putString("key", testproductname);
FragmentDialog newFragment = new FragmentDialog();
newFragment.setArguments(args);
newFragment.show(getActivity().getSupportFragmentManager(), "TAG");
showTheDialog();
}
});
}
protected void showTheDialog() {
FragmentManager fm = getActivity().getSupportFragmentManager();
FragmentDialog overlay = new FragmentDialog();
overlay.show(fm, "FragmentDialog");
}
片段對話框
public class FragmentDialog extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
//dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.YELLOW));
dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
return dialog;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle
savedInstanceState) {
View view = inflater.inflate(R.layout.prompt_quantity, container);
// tab slider
sectionsPagerAdapter = new SectionsPagerAdapter(getChildFragmentManager());
// Set up the ViewPager with the sections adapter.
viewPager = (ViewPager) view.findViewById(R.id.modifierpager);
viewPager.setAdapter(sectionsPagerAdapter);
Bundle mArgs = getArguments();
pName = mArgs.getString("key","asdasd");
final TextView tpn = (TextView)getView().findViewById(R.id.gtestproductname);
tpn.setText(pName);
}
newFragment.show(getActivity().getSupportFragmentManager(), "TAG");
showTheDialog();
您無需調用show兩次,此邏輯兩次繪制視圖。 這就是為什么您有異常。 刪除第二個。
