第五章常用UI界面控件

除了前面介绍的TextView、EditView、Button、CheckBox和RadioGroup等控件以外，Android系统还提供了很多其他界面控件，例如Toast信息提示，对话框、下拉列表、选项卡、日期时间控件和菜单等

5.1信息提示和对话框

5.1.1Toast

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <TextView  
        android:id="@+id/tv_button"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:text="Toast示例\n"
        />
    <Button android:id="@+id/btn_1" 
        android:text="显示短时的Toast" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" /> 
    <Button android:id="@+id/btn_2" 
        android:text="显示长时的Toast" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" /> 
    <Button android:id="@+id/btn_3" 
        android:text="在Toast中显示图片" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" /> 
</LinearLayout>

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

public class MainActivity extends Activity {
	private Button Btn1,Btn2 ,Btn3 ;//实例化两个按钮
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		Btn1 =(Button)findViewById(R.id.btn_1 );
		Btn2 = (Button)findViewById(R.id.btn_2);
		Btn3 = (Button)findViewById(R.id.btn_3);
		Btn1.setOnClickListener( new Button.OnClickListener(){   //侦听按钮1被按下的动作
			public void onClick(View v) {
			  Toast.makeText(getApplicationContext(), "短时的Toast信息", Toast.LENGTH_SHORT).show();
			}
		});
		Btn2.setOnClickListener( new Button.OnClickListener(){   //侦听按钮1被按下的动作
			public void onClick(View v) {
			  Toast.makeText(getApplicationContext(), "长时的Toast信息", Toast. LENGTH_LONG).show();
			}
		});

		Btn3.setOnClickListener(new Button.OnClickListener() {
		    public void onClick(View v)  {
		      Toast toast = new Toast(getApplicationContext());  //toast实例化
		      ImageView myview = new ImageView(getApplicationContext());  //实例化ImageView
		      myview.setImageResource(R.drawable.fw8005);  //和指定的图片关联
		      toast.setView(myview);  //将toast实例和图片实例关联
		      toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);  //定位图片显示位置，否则以默认位置显示
		      toast.show();  //显示toast
		    }
		});
	}

}

5.1.2 状态栏提醒 Notification

与Toast不同，Notification是显示在状态栏的提示信息，痛呀它也不会打断用户当前的操作，而且它支持更复杂的点击事件响应

import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;


public class MainActivity extends Activity {
	private NotificationManager mNotificationManager;   
	private int SIMPLE_NOTFICATION_ID;  
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
        //创建 NotificationManager对象，负责“发出”与“取消”Notification   
        //下面创建 Notification ，参数依次为icon的资源id、在状态栏上展示的滚动信息、时间。
        final Notification notifyDetails = new Notification(R.drawable.image1,"这是Notification提示信息",System.currentTimeMillis());   
        Button btnstart = (Button)findViewById(R.id.btn_1);   
        Button btncancel = (Button)findViewById(R.id.btn_2);  
        Button btnfinish = (Button)findViewById(R.id.btn_3);
        final TextView txt= (TextView)findViewById(R.id.tv_message);
        
        btnstart.setOnClickListener(new OnClickListener() {   //“显示提示”按钮对应的点击事件
           public void onClick(View v) {   
              Context context = getApplicationContext();   
              CharSequence contentTitle = "您好";   
              CharSequence contentText = "这是给您的Notification提示";   
              txt.setText("Notification示例----您选中了显示提示\n");
              Intent notifyIntent = new Intent(android.content.Intent.ACTION_VIEW);   
              //PendingIntent 为Intent的包装，这里是启动Intent的描述。
              //PendingIntent.getActivity 返回的PendingIntent表示此PendingIntent实例中的Intent是用于启动 Activity 的Intent。
              //PendingIntent.getActivity的参数依次为：Context，发送者的请求码（可以填0）、用于系统发送的Intent、标志位。
              PendingIntent intent = PendingIntent.getActivity(MainActivity.this, 0, notifyIntent, android.content.Intent.FLAG_ACTIVITY_NEW_TASK);   
          
              //notifyDetails.setLatestEventInfo(context, contentTitle, contentText, intent);   
              mNotificationManager.notify(SIMPLE_NOTFICATION_ID, notifyDetails);   
        	}
         });   
        btncancel.setOnClickListener(new OnClickListener() {   //“关闭程序”按钮对应的点击事件
            public void onClick(View v) {   
            	txt.setText("Notification示例----您取消了显示提示\n");
            	mNotificationManager.cancel(SIMPLE_NOTFICATION_ID);               
            }   
        });
        btnfinish.setOnClickListener(new OnClickListener() {   //“关闭程序”按钮对应的点击事件
            public void onClick(View v) {   
               finish();//退出应用程序
            }   
        });
