 其他代码同上一案例

使用PopupWindow

package com.example.myapplication;

import android.app.Activity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.widget.Button;
import android.widget.PopupWindow;

public class MainActivity extends Activity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        View root = this.getLayoutInflater().inflate(R.layout.login, null);
        final PopupWindow popupWindow = new PopupWindow(root, 560, 720);
        Button button = findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                popupWindow.showAtLocation(findViewById(R.id.button), Gravity.CENTER, 20, 20);
            }
        });
        findViewById(R.id.close).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                popupWindow.dismiss();
            }
        });
    }

}

使用ProgressDialog创建进度对话框

    ProgressDialog pd1, pd2;
    Handler handler = new Handler() {
        public void handleMessage(Message msg) {
            if (msg.what == 0x123) {
                pd2.setProgress(progressStatus);
            }
        }
    };

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }

    public void showSpinner(View source) {

        pd1.setTitle("任务正在执行");     //标题
        pd1.setMessage("任务正在在执行中。。。。");     //内容
        pd1.setCancelable(true);      //能用取消按钮
        pd1.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);      //进度条风格

        pd2 = new ProgressDialog(MainActivity.this);
        pd2.setMax(MAX_PROGRESS);
        pd2.setTitle("任务完成百分比");
        pd2.setMessage("耗时任务百分比");
        pd2.setCancelable(false);
        pd2.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        pd2.setIndeterminate(false);
        pd2.show();
        new Thread(){
            public void run(){
                while (progressStatus<MAX_PROGRESS){
                    progressStatus=MAX_PROGRESS*doWork()/data.length;
                    handler.sendEmptyMessage(0x123);
                }
                if(progressStatus>=MAX_PROGRESS){
                    pd2.dismiss();
                }
            }
        }.start();
    }
    public int doWork(){
        data[hasData++]=(int)(Math.random()*100);
        try {
            Thread.sleep(100);
        }catch (InterruptedException e){
            e.printStackTrace();
        }
        return hasData;
    }
}

使用DatePickerDialog，TimePickerDialog

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">
    <EditText
        android:id="@+id/show"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />
    <Button
        android:id="@+id/dateBn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="日期按钮"
        />
    <Button
        android:id="@+id/timeBn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="时间按钮"
        />

</LinearLayout>
