Android studio 提示框Toast 弹出框AlertDialog 多种提示方法Javacuixiaoyu的博客-

1、Toast

Handler handler = new Handler(Looper.getMainLooper()); handler.post(new Runnable() { @Override public void run() { //放在UI线程弹Toast         Toast.makeText(Setting.this, "正在更新请稍后", Toast.LENGTH_LONG).show(); } }); 

2、弹出框
2.1默认样式

 android.support.v7.app.AlertDialog.Builder builder = new android.support.v7.app.AlertDialog.Builder(AlertDialogActivity.this); builder.setTitle("提示"); builder.setMessage("更新成功"); builder.setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) {         Toast.makeText(AlertDialogActivity.this, "确定了",Toast.LENGTH_SHORT).show(); } }); builder.setNeutralButton("取消", null); builder.show(); 

2.2单选

final String[] gender = new String[]{"java","android"}; android.support.v7.app.AlertDialog.Builder builder1=new android.support.v7.app.AlertDialog.Builder(AlertDialogActivity.this); builder.setTitle("请选择"); builder.setItems(gender, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) {             ToastUtil.showMsg(AlertDialogActivity.this,gender[which]); } }); builder.show(); 

android.support.v7.app.AlertDialog.Builder builder2=new android.support.v7.app.AlertDialog.Builder(AlertDialogActivity.this); builder.setTitle("你最喜欢吃一下那种菜肴："); final String[] dish =new String[]{"红烧牛肉","粉蒸排骨"}; builder.setSingleChoiceItems(dish, 1, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) {         ToastUtil.showMsg(AlertDialogActivity.this,dish[which]);          dialog.dismiss(); } }); builder.setCancelable(false); builder.show(); break; 

2.3多选框

String[] dessert = new String[]{"抹茶千层","芒果拿破仑"}; boolean[] begin = new boolean[]{false,false}; android.support.v7.app.AlertDialog.Builder builder3=new android.support.v7.app.AlertDialog.Builder(AlertDialogActivity.this); builder.setTitle("你吃过以下哪些甜点"); builder.setMultiChoiceItems(dessert, begin, new DialogInterface.OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int which, boolean isChecked) { } }); builder.setPositiveButton("确认",null); builder.setNegativeButton("取消",null); builder.show(); break; 

用的次数很多可以封装一下
Prompt.java

public class Promptextends MyApplication { public static void Bill_headtk(final Bill_head ym,final String nr) { new Thread(new Runnable() { @Override public void run() {                 Handler handler = new Handler(Looper.getMainLooper());                 handler.post(new Runnable() { @Override public void run() { //放在UI线程弹Toast                         AlertDialog.Builder builder=new AlertDialog.Builder(ym);                         builder.setTitle("提示");                         builder.setMessage(nr);                         builder.setPositiveButton("确定",null);                         builder.show(); } }); } }).start(); } } 

在Bill_head.java中调用

Prompt.Bill_headtk(Bill_head.this, "请输入");
