Java代码

LoginFragmentDialog.java

[code]package com.example.administrator.myapplication;

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;

/**
 * Created by Administrator on 2015/11/30.
 */
public class LoginFragmentDialog extends DialogFragment{

    public interface LoginInputListener {
        public void onLoginPutData(String info, 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.login_fragment_layout, null);
        final EditText info = (EditText)view.findViewById(R.id.edt_userinfo);
        final EditText password = (EditText)view.findViewById(R.id.edt_password);

        builder.setView(view)
                .setPositiveButton("登录", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        LoginInputListener loginListener = (LoginInputListener)getActivity();
                        loginListener.onLoginPutData(info.getText().toString(), password.getText().toString());
                    }
                })
                .setNegativeButton("取消", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {

                    }
                });

        return builder.create();
    }
}

MainActivity.java

[code]package com.example.administrator.myapplication;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity implements View.OnClickListener, LoginFragmentDialog.LoginInputListener {

    private Button btn_edit = null;
    private Button btn_login = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        findView();
    }

    private void findView() {
        btn_edit = (Button) findViewById(R.id.btn_edit_dialog);
        btn_login = (Button) findViewById(R.id.btn_login);
        btn_edit.setOnClickListener(this);
        btn_login.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        int Id = v.getId();
        switch (Id) {
            case R.id.btn_edit_dialog:
                EditFragmentDialog edit = new EditFragmentDialog();
                edit.show(MainActivity.this.getFragmentManager(), "EditDialog");
                break;
            case R.id.btn_login:
                LoginFragmentDialog login = new LoginFragmentDialog();
                login.show(MainActivity.this.getFragmentManager(), "login");
                break;
        }
    }

    @Override
    public void onLoginPutData(String info, String password) {
        Toast.makeText(MainActivity.this, info + "\n" + password, Toast.LENGTH_SHORT).show();
    }
}

当然还有编辑框的例子
