【问题描述】:
我有一个问题,我使用 bundle 将数据从片段发送到对话框片段,但是当我单击片段布局中的按钮时出现问题,它成功地从片段中获取数据,但在我的对话框片段中它得到空值,当我调试时,我发现我的对话框片段运行了两次,这就是为什么我得到空值。任何解决这个问题的建议,对不起我的英语,希望能理解我的问题。
这是我的 onclick 将数据传递给我的对话框片段
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");
}
片段对话框
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);
}
【问题讨论】:
-
什么是
showTheDialog()?看来你之前已经打电话给newFragment.show了…… -
谢谢,我更新了我的问题,showThDialog() 用于提示我的对话片段
-
如果您从
showTheDialog()调用对话框片段,它将再次以空值显示它,并且您正在调用以在上一行newFragment.show(getActivity().getSupportFragmentManager(), "TAG"); //here you are calling to show the fragment和showTheDialog(); //Are you showing the fragment again here?中显示对话框 -
一次显示 2 个对话框?
-
尝试注释掉
showTheDialog函数调用,看看是否解决问题
