Dialog的基本方法

//创建Dialog
AlertDialog.Builderbuilder=newAlertDialog.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(CharSequencetext,DialogInterface.OnClickListenerlistener)
//取消按钮
setNegativeButton(CharSequencetext,DialogInterface.OnClickListenerlistener)
//忽略
setNeutralButton(CharSequencetext,DialogInterface.OnClickListenerlistener)
//显示对话框
show();

系统样式

1.下拉列表

AlertDialog.Builderbuilder=newAlertDialog.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
finalString[]cities={"北京","上海","广州","深圳","杭州"};
builder.setItems(cities,newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){
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.Builderbuilder=newAlertDialog.Builder(MainActivity.this);
builder.setIcon(R.drawable.ic_launcher);
builder.setTitle("请选择性别");
finalString[]sex={"男","女"};
//第二个参数指定默认哪个单选框被勾中
builder.setSingleChoiceItems(sex,1,newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){
Toast.makeText(MainActivity.this,"性别为："+sex[which],Toast.LENGTH_SHORT).show();
}
});
builder.setPositiveButton("确定",newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){

}
});
builder.setNegativeButton("取消",newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){

}
});
builder.show();

3.多选框列表

Stringstr;
AlertDialog.Builderbuilder=newAlertDialog.Builder(MainActivity.this);
builder.setIcon(R.drawable.ic_launcher);
builder.setTitle("选择你想看的电视剧");
finalString[]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,newDialogInterface.OnMultiChoiceClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich,booleanisChecked){
if(isChecked){
str.append(hobbies[which]+",");
}
Toast.makeText(MainActivity.this,"选择的是："+str.toString(),Toast.LENGTH_SHORT).show();
}
});
builder.setPositiveButton("确定",newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){

}
});
builder.setNegativeButton("取消",newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){

}
});
builder.show();

4.等待对话框

ProgressDialogwaitingDialog=newProgressDialog(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

intMAXPD=100;
ProgressDialogprogressDialog=newProgressDialog(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

publicclassCustomDialogextendsDialog{
//标题
protectedTextViewhintTv;
//左边按钮
protectedButtondoubleLeftBtn;
//右边按钮
protectedButtondoubleRightBtn;
//输入框
publicEditTexteditText;
publicCustomDialog(Contextcontext){
super(context,R.style.CustomDialogStyle);
}
@Override
protectedvoidonCreate(BundlesavedInstanceState){
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
publicvoidsetRightButton(StringrightStr,View.OnClickListenerclickListener){
doubleRightBtn.setOnClickListener(clickListener);
doubleRightBtn.setText(rightStr);
}
//设置左键文字和点击事件
publicvoidsetLeftButton(StringleftStr,View.OnClickListenerclickListener){
doubleLeftBtn.setOnClickListener(clickListener);
doubleLeftBtn.setText(leftStr);
}
//设置提示内容
publicvoidsetHintText(Stringstr){
hintTv.setText(str);
hintTv.setVisibility(View.VISIBLE);
}
//给两个按钮设置文字
publicvoidsetBtnText(StringleftStr,StringrightStr){
doubleLeftBtn.setText(leftStr);
doubleRightBtn.setText(rightStr);
}
}

2.自定义Style



@null

@color/transparent

true

true

false

@null

true

@color/white
@color/white

3.自定义布局

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(newView.OnSystemUiVisibilityChangeListener(){
@Override
publicvoidonSystemUiVisibilityChange(intvisibility){
intuiOptions=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

CustomDialogdialog=newCustomDialog(this);
dialog.setHintText("请输入密码");
dialog.setLeftButton("取消",newView.OnClickListener(){
@Override
publicvoidonClick(Viewv){
dialog.dismiss();
}
});
dialog.setRightButton("确定",newView.OnClickListener(){
@Override
publicvoidonClick(Viewv){

}
});
dialog.show();
