fragment文件

package com.qykl.dialogfragment;

import com.example.dilaogfragdemo.R;

import android.app.AlertDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.EditText;

public class LoginDialogFragment extends DialogFragment
{

private EditText mUsername;
private EditText mPassword;

public interface LoginInputListener
{
void onLoginInputComplete(String username, String password);
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.fragment_login_dialog, null);
mUsername = (EditText) view.findViewById(R.id.id_txt_username);
mPassword = (EditText) view.findViewById(R.id.id_txt_password);
builder.setView(view)
.setPositiveButton("Sign in",
new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int id)
{
LoginInputListener listener = (LoginInputListener) getActivity();
listener.onLoginInputComplete(mUsername
.getText().toString(), mPassword
.getText().toString());
}
}).setNegativeButton("Cancel", null);
return builder.create();
}
}

在主程序中调用

LoginDialogFragment dialog = new LoginDialogFragment();
dialog.show(getFragmentManager(), "loginDialog");

如果需要交互

可以在dialog中添加interface
