接下来看代码：

public class MyDialog extends Dialog {    private Button yes;//确定按钮    private Button no;//取消按钮    private TextView titleTv;//消息标题文本    private TextView messageTv;//消息提示文本    private String titleStr;//从外界设置的title文本    private String messageStr;//从外界设置的消息文本    private View view;    //确定文本和取消文本的显示内容    private String yesStr, noStr;    private onNoOnclickListener noOnclickListener;//取消按钮被点击了的监听器    private onYesOnclickListener yesOnclickListener;//确定按钮被点击了的监听器        public void setNoOnclickListener(String str, onNoOnclickListener onNoOnclickListener) {        if (str != null) {            noStr = str;        }        this.noOnclickListener = onNoOnclickListener;    }        public void setYesOnclickListener(String str, onYesOnclickListener onYesOnclickListener) {        if (str != null) {            yesStr = str;        }        this.yesOnclickListener = onYesOnclickListener;    }    public MyDialog(Context context) {        super(context, R.style.MyDialog);    }    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.mydialog);        //按空白处不能取消动画        setCanceledOnTouchOutside(false);        //初始化界面控件        initView();        //初始化界面数据        initData();        //初始化界面控件的事件        initEvent();    }        private void initEvent() {        //设置确定按钮被点击后，向外界提供监听        yes.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if (yesOnclickListener != null) {                    yesOnclickListener.onYesClick();                }            }        });        //设置取消按钮被点击后，向外界提供监听        no.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if (noOnclickListener != null) {                    noOnclickListener.onNoClick();                }            }        });    }        private void initData() {        //如果用户自定了title和message        if (titleStr != null) {            titleTv.setText(titleStr);        }        if (messageStr != null) {            messageTv.setText(messageStr);        }        //如果设置按钮的文字        if (yesStr != null) {            yes.setText(yesStr);        }        if (noStr != null) {            no.setVisibility(View.VISIBLE);            view.setVisibility(View.VISIBLE);            no.setText(noStr);        } else {            no.setVisibility(View.GoNE);            view.setVisibility(View.GONE);        }    }        private void initView() {        yes = (Button) findViewById(R.id.yes);        no = (Button) findViewById(R.id.no);        titleTv = (TextView) findViewById(R.id.title);        messageTv = (TextView) findViewById(R.id.message);        view = findViewById(R.id.view_dialog);    }        public void setTitle(String title) {        titleStr = title;    }        public void setMessage(String message) {        messageStr = message;    }        public interface onYesOnclickListener {        public void onYesClick();    }    public interface onNoOnclickListener {        public void onNoClick();    }}

Xml文件：

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="Http://schemas.android.com/apk/res/android"                android:layout_width="match_parent"                android:layout_height="match_parent"               >    <LinearLayout        android:layout_width="260dp"        android:layout_height="wrap_content"        android:background="@drawable/mydialog_shape"        android:orientation="vertical"        android:layout_centerVertical="true"        android:layout_centerHorizontal="true">        <TextView            android:id="@+id/title"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center"            android:layout_margin="15dp"            android:gravity="center"            android:text="消息提示"            android:textColor="#333333"            android:textSize="16sp" />        <TextView            android:id="@+id/message"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_marginLeft="20dp"            android:layout_marginRight="20dp"            android:layout_gravity="center"            android:textColor="#666666"            android:text="提示消息" />        <View            android:layout_width="match_parent"            android:layout_height="1px"            android:layout_marginTop="15dp"            android:background="#E4E4E4" />        <LinearLayout            android:layout_width="match_parent"            android:layout_height="40dp"            android:orientation="horizontal">            <Button                android:id="@+id/no"                android:layout_width="0dp"                android:layout_height="match_parent"                android:layout_marginLeft="10dp"                android:layout_weight="1"                android:background="@null"                android:gravity="center"                android:singleLine="true"                android:text="No"                android:textColor="#7D7D7D"                android:visibility="gone"                android:textSize="16sp" />            <View                android:id="@+id/view_dialog"                android:layout_width="1px"                android:layout_height="match_parent"                android:background="#E4E4E4" />            <Button                android:id="@+id/yes"                android:layout_width="0dp"                android:layout_height="match_parent"                android:layout_marginRight="10dp"                android:layout_weight="1"                android:background="@null"                android:gravity="center"                android:singleLine="true"                android:text="Yes"                android:textColor="#38ADFF"                android:textSize="16sp" />        </LinearLayout>    </LinearLayout></RelativeLayout>

调用的方法：

  myDialog = new MyDialog(activity);                            myDialog.setTitle("提示");                            myDialog.setMessage("您输入的关键字未查询到信息，请重新输入");                            myDialog.setYesOnclickListener("确定", new MyDialog.onYesOnclickListener() {                                @Override                                public void onYesClick() {                                    myDialog.dismiss();                                }                            });                            myDialog.show();

这是一个调用只含有确认键的方法，通过mydialog中传的str来进行判断，gone或者vs:

   if (noStr != null) {            no.setVisibility(View.VISIBLE);            view.setVisibility(View.VISIBLE);            no.setText(noStr);        } else {            no.setVisibility(View.GONE);            view.setVisibility(View.GONE);        }

调用俩个按键：

    myDialog = new MyDialog(activity);                    myDialog.setTitle("指纹关闭确认");                    myDialog.setMessage("确认关闭指纹登陆？");                    myDialog.setYesOnclickListener("确定", new MyDialog.onYesOnclickListener() {                        @Override                        public void onYesClick() {                            SharedPreferenceUtil.setInfoToShared("Z", "N");                            myDialog.dismiss();                        }                    });                    myDialog.setNoOnclickListener("取消", new MyDialog.onNoOnclickListener() {                        @Override                        public void onNoClick() {                            cbFingerprint.setChecked(true);                            myDialog.dismiss();                        }                    });                    myDialog.show();
