dialog的基本方法
//创建dialog alertdialog.builder builder = new alertdialog.builder(mainactivity.this); //设置标题图标 builder.seticon(r.drawable.ic_launcher); //设置标题 builder.settitle("这是一个对话框"); //设置信息 builder.setmessage("是否要跳转?"); //确定按钮 setpositivebutton(charsequence text, dialoginterface.onclicklistener listener) //取消按钮 setnegativebutton (charsequence text, dialoginterface.onclicklistener listener) //忽略 setneutralbutton (charsequence text, dialoginterface.onclicklistener listener) //显示对话框 show();
系统样式
1.下拉列表
alertdialog.builder builder = new alertdialog.builder(mainactivity.this); builder.seticon(r.drawable.ic_launcher); builder.settitle("选择一个城市"); //下拉列表的数据源 final string[] cities = {"北京", "上海", "广州", "深圳", "杭州"}; builder.setitems(cities, new dialoginterface.onclicklistener(){ @override public void onclick(dialoginterface dialog, int which){ toast.maketext(mainactivity.this, "你选择的城市为:" + cities[which], toast.length_short).show(); } }); builder.show();
2.单选框列表
alertdialog.builder builder = new alertdialog.builder(mainactivity.this); builder.seticon(r.drawable.ic_launcher); builder.settitle("请选择性别"); final string[] sex = {"男", "女"}; //第二个参数指定默认哪个单选框被勾中 builder.setsinglechoiceitems(sex, 1, new dialoginterface.onclicklistener(){ @override public void onclick(dialoginterface dialog, int which){ toast.maketext(mainactivity.this, "性别为:" + sex[which], toast.length_short).show(); } }); builder.setpositivebutton("确定", new dialoginterface.onclicklistener(){ @override public void onclick(dialoginterface dialog, int which){ } }); builder.setnegativebutton("取消", new dialoginterface.onclicklistener(){ @override public void onclick(dialoginterface dialog, int which){ } }); builder.show();
3.多选框列表
string str;
alertdialog.builder builder = new alertdialog.builder(mainactivity.this); builder.seticon(r.drawable.ic_launcher); builder.settitle("选择你想看的电视剧"); final string[] hobbies = {"廷禧攻略", "扶摇", "香蜜沉沉烬如霜", "如懿传"}; //第二个参数代表哪几个选项被选择,需要传递一个boolean[]数组进去,其长度要和第一个参数的长度相同,如果null表示都不选 builder.setmultichoiceitems(hobbies, null, new dialoginterface.onmultichoiceclicklistener(){ @override public void onclick(dialoginterface dialog, int which, boolean ischecked){ if(ischecked){ str.append(hobbies[which] + ", "); } toast.maketext(mainactivity.this, "选择的是:" + str.tostring(), toast.length_short).show(); } }); builder.setpositivebutton("确定", new dialoginterface.onclicklistener(){ @override public void onclick(dialoginterface dialog, int which){ } }); builder.setnegativebutton("取消", new dialoginterface.onclicklistener(){ @override public void onclick(dialoginterface dialog, int which){ } }); builder.show();
4.等待对话框
progressdialog waitingdialog= new progressdialog(mainactivity.this); waitingdialog.settitle("等待加载中,请稍后..."); waitingdialog.setmessage("等待中..."); waitingdialog.setindeterminate(true);//采用不确定式的进度条 waitingdialog.setcancelable(false);//点击外部不取消对话框 waitingdialog.show();
5.进度条对话框
int maxpd = 100; progressdialog progressdialog = new progressdialog(mainactivity.this); progressdialog.setprogress(0);//设置默认值 progressdialog.settitle("正在下载"); progressdialog.setprogressstyle(progressdialog.style_horizontal);//进度条样式 progressdialog.setmax(maxpd);//设置最大值 progressdialog.show();
自定义dialog
1.继承dialog
public class customdialog extends dialog { //标题 protected textview hinttv; //左边按钮 protected button doubleleftbtn; //右边按钮 protected button doublerightbtn; //输入框 public edittext edittext; public customdialog(context context) { super(context, r.style.customdialogstyle); } @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); this.setcancelable(false); // 是否可以撤销 setcontentview(r.layout.dialog_custom); hinttv = findviewbyid(r.id.tv_common_dialog_hint); doubleleftbtn = findviewbyid(r.id.btn_common_dialog_double_left); doublerightbtn = findviewbyid(r.id.btn_common_dialog_double_right); edittext = findviewbyid(r.id.et_common_dialog); } //置右键文字和点击事件 public void setrightbutton(string rightstr, view.onclicklistener clicklistener) { doublerightbtn.setonclicklistener(clicklistener); doublerightbtn.settext(rightstr); } //设置左键文字和点击事件 public void setleftbutton(string leftstr, view.onclicklistener clicklistener) { doubleleftbtn.setonclicklistener(clicklistener); doubleleftbtn.settext(leftstr); } //设置提示内容 public void sethinttext(string str) { hinttv.settext(str); hinttv.setvisibility(view.visible); } //给两个按钮 设置文字 public void setbtntext(string leftstr, string rightstr) { doubleleftbtn.settext(leftstr); doublerightbtn.settext(rightstr); } }
2.自定义style
<style name="customdialogstyle" parent="@android:style/theme.dialog"> <!-- 边框 --> <item name="android:windowframe">@null</item> <!-- 背景透明 --> <item name="android:windowbackground">@color/transparent</item> <!-- 无标题 --> <item name="android:windownotitle">true</item> <!-- 是否浮现在activity之上 --> <item name="android:windowisfloating">true</item> <!-- 半透明 --> <item name="android:windowistranslucent">false</item> <!-- 背景模糊 --> <item name="android:windowcontentoverlay">@null</item> <!-- 允许对话框的背景变暗 --> <item name="android:backgrounddimenabled">true</item> <!-- 字体颜色 --> <item name="android:textcolor">@color/white</item> <item name="android:edittextcolor">@color/white</item> </style>
3.自定义布局
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/ll_common_dialog_layout" android:layout_width="500dp" android:layout_height="250dp" android:layout_margin="5dp" android:background="@drawable/background_info" android:orientation="vertical" android:gravity="center"> <!--提示信息--> <textview android:id="@+id/tv_common_dialog_hint" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:textcolor="@color/white" android:textsize="27sp"/> <edittext android:id="@+id/et_common_dialog" android:layout_width="300dp" android:layout_height="wrap_content" android:textcolor="@color/back" android:inputtype="text|textnosuggestions" tools:ignore="labelfor" android:hint="请输入密码"/> <!--底部按钮--> <linearlayout android:id="@+id/ll_common_dialog_double" android:layout_width="360dp" android:layout_height="60dp" android:layout_margin="20dp" android:orientation="horizontal"> <button android:id="@+id/btn_common_dialog_double_left" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="@drawable/btnselector" android:gravity="center" android:textcolor="@color/white" android:textsize="27dp"/> <button android:id="@+id/btn_common_dialog_double_right" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="@drawable/btnselector" android:gravity="center" android:textcolor="@color/white" android:textsize="27dp"/> </linearlayout> </linearlayout>
4.ipad隐藏底部虚拟按键
//弹出dialog时隐藏底部虚拟按键 dialog.getwindow().getdecorview().setsystemuivisibility(view.system_ui_flag_hide_navigation); dialog.getwindow().getdecorview().setonsystemuivisibilitychangelistener(new view.onsystemuivisibilitychangelistener() { @override public void onsystemuivisibilitychange(int visibility) { int uioptions =view.system_ui_flag_hide_navigation; if (build.version.sdk_int >= 19) { uioptions |= 0x00001000; } else { uioptions |= view.system_ui_flag_low_profile; } dialog.getwindow().getdecorview().setsystemuivisibility(uioptions); } });
5.使用自定义dialog
customdialog dialog = new customdialog(this); dialog.sethinttext("请输入密码"); dialog.setleftbutton("取消", new view.onclicklistener() { @override public void onclick(view v) { dialog.dismiss(); } }); dialog.setrightbutton("确定", new view.onclicklistener() { @override public void onclick(view v) { } }); dialog.show();
