1.自定义dialog的用法

YouMengDialog userMsgDialog=null;

private void initTipDialog() {
    userMsgDialog = new YouMengDialog (this);
    userMsgDialog.setTitle("系统提示！");
    userMsgDialog.setMessage("提示的内容！");
    userMsgDialog.setCanceledOnTouchOutside(false);

    userMsgDialog.setButton1("取消", new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        userMsgDialog.dismiss();

        }
    });

    userMsgDialog.setButton2("确定", new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        userMsgDialog.dismiss();

        }
    });
    userMsgDialog.show();
}

2.dialog的java代码

public class YouMengDialog extends Dialog {
    private View contentView;
    public YouMengDialog(Context context){
        super(context, R.style.tran_AlertDialog);
        LayoutInflater inflater = LayoutInflater.from(context);
        this.contentView = inflater.inflate(R.layout.dialog, null);
    }
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(contentView);
        Window window = this.getWindow();
        WindowManager.LayoutParams lp = window.getAttributes();
        Display d = window.getWindowManager().getDefaultDisplay();
        lp.width = (int) (d.getWidth() * 0.9F);
        window.setAttributes(lp);
    }

//设置提示框标题
    public void setTitle(String title){
        final TextView textView = (TextView) contentView.findViewById(R.id.title);
        textView.setText(title);
    }
//设置提示的内容
    public void setMessage(String message){
        final TextView textView = (TextView) contentView.findViewById(R.id.message);
        textView.setText(message);
    }
//对提示框的第一个按键（取消按钮）设置，title：按钮上的文字，onclicklistener ：触发的事件
    public void setButton(String title,View.OnClickListener onClickListener){
        final Button button = (Button) contentView.findViewById(R.id.dialogButton);
        button.setText(title);
        button.setOnClickListener(onClickListener);
    }

//当只需要一个确定键的时候让取消键隐藏
    public void setButtonGone(){
        Button button = (Button) contentView.findViewById(R.id.dialogButton);
        button.setVisibility(View.GONE);

    }

//对提示框的第二个按键（确定按钮）设置，title：按钮上的文字，onclicklistener ：触发的事件

    public void setButton2(String title,View.OnClickListener onClickListener){
        final Button button = (Button) contentView.findViewById(R.id.dialogButton2);
        button.setText(title);
        button.setOnClickListener(onClickListener);
    }
}

3.用到的样式表

<style name="tran_AlertDialog" parent="@android:style/Theme.Dialog">
    <item name="android:windowFrame">@null</item>
    <!-- 边框 -->
    <item name="android:windowIsFloating">true</item>
    <!-- 是否浮现在activity之上 -->
    <item name="android:windowIsTranslucent">true</item>
    <!-- 半透明 -->
    <item name="android:windowNoTitle">true</item>
    <!-- 无标题 -->
    <item name="android:windowBackground">@drawable/gray_corners_border</item>
    <!-- 自己想要的背景 -->
    <item name="android:backgroundDimEnabled">true</item>
    <!-- 模糊 -->
</style>
