Android studio 提示框Toast 弹出框AlertDialog 多种提示方法

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");
