AndroidDialog详解及实例代码
概述：
Android开发中最常用的就是Dialog类，除了自定义dialog布局，最多的就是用在弹出对话框、进度条、输入框、单选、复选框。
1、选择对话框：
AlertDialog.Builderdialog=newAlertDialog.Builder(this);
dialog.setTitle("选择对话框");
dialog.setMessage("请选择确认或取消");
dialog.setCancelable(false);//设置按下返回键不能消失
dialog.setPositiveButton("确认",newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){
Toast.makeText(MainActivity.this,"您选择了确认",Toast.LENGTH_LONG).show();
}
});
dialog.setNegativeButton("取消",newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){
Toast.makeText(MainActivity.this,"您选择了取消",Toast.LENGTH_LONG).show();
}
});
dialog.show();//显示弹出窗口
2、进度条
ProgressDialogprogressDialog=newProgressDialog(this);
progressDialog.setTitle("显示进度条");
progressDialog.setMessage("加载中...");
progressDialog.setCancelable(true);
progressDialog.show();
3、弹出输入框
AlertDialog.Builderbuilder=newAlertDialog.Builder(this);
builder.setTitle("弹出输入框");
builder.setMessage("输入内容");
finalEditTexteditText=newEditText(this);
builder.setView(editText);
builder.setPositiveButton("确定",newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){
Toast.makeText(MainActivity.this,"您输入了"+editText.getText().toString(),Toast.LENGTH_SHORT).show();
}
});
builder.setNegativeButton("取消",null);
builder.show();
4、弹出单选框
finalAlertDialog.Builderbuilder=newAlertDialog.Builder(this);
builder.setTitle("弹出单选框");
finalString[]choice=newString[]{"Java","C++","PHP"};
builder.setSingleChoiceItems(choice,0,
newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){
Toast.makeText(MainActivity.this,"您选择了"+choice[which],Toast.LENGTH_LONG).show();
dialog.dismiss();//让窗口消失
}
});
builder.create().show();
5、弹出复选框
finalAlertDialog.Builderbuilder=newAlertDialog.Builder(this);
builder.setTitle("弹出多选框");
finalString[]choice=newString[]{"Android","IOS","WindosPhone"};//选择项
finalboolean[]isCheck=newboolean[choice.length];//是否被选中
builder.setMultiChoiceItems(choice,null,
newDialogInterface.OnMultiChoiceClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich,booleanisChecked){
if(isChecked==true)
isCheck[which]=true;
elseif(isChecked==false)
isCheck[which]=false;
}
});
builder.setNegativeButton("取消",null);
builder.setPositiveButton("确定",newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){
StringisSelected="您选择了";
for(inti=0;i
6、自定义布局的Dialog
AlertDialog.Builderbuilder=newAlertDialog.Builder(this);
finalAlertDialogdialog=builder.create();
Viewview=View.inflate(this,R.layout.personal_modifyhead_dialog,null);
dialog.setView(view,0,0,0,0);//设置边距为0,保证在2.x的版本上运行没问题
dialog.show();
AutoRelativeLayoutrl_photograph=(AutoRelativeLayout)view.findViewById(R.id.rl_photograph);
rl_photograph.setOnClickListener(newView.OnClickListener(){
@Override
publicvoidonClick(Viewv){
presenter.modiftHeadFromPhotograph();
dialog.dismiss();
}
});
AutoRelativeLayoutrl_album=(AutoRelativeLayout)view.findViewById(R.id.rl_album);
rl_album.setOnClickListener(newView.OnClickListener(){
@Override
publicvoidonClick(Viewv){
presenter.modifyHeadFromAlbum();
dialog.dismiss();
}
});
上面就是日常开发中常用的一些，在此记录，以便日后查询。
