package com.example.jjy.myapplication; import android.app.Dialog; import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.widget.Button; import android.widget.TextView; /** * Created by jjy on 16-5-15. */ public class MyDialog extends Dialog{ private Button positiveButton, negativeButton; private TextView contenttv; public MyDialog(Context context) { super(context,R.style.mydialog); View view = LayoutInflater.from(getContext()).inflate(R.layout.mydialoglayout, null); //通过LayoutInflater获取布局 contenttv = (TextView) view.findViewById(R.id.title); positiveButton = (Button) view.findViewById(R.id.acceptbtn); negativeButton = (Button) view.findViewById(R.id.refusebtn); setContentView(view); //设置view } //设置内容 public void setContent(String content) { contenttv.setText(content); } //确定按钮监听 public void setOnPositiveListener(View.OnClickListener listener){ positiveButton.setOnClickListener(listener); }//否定按钮监听 public void setOnNegativeListener(View.OnClickListener listener){ negativeButton.setOnClickListener(listener); } }

R.style.mydialog 对话框属性在 values/styles.xml中设置：
