消息提示 Toast Notification

带图片的Toast

效果图如下：

代码如下：

Button toa = (Button) findViewById(R.id.btn1);

        toa.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {

                Toast t = Toast.makeText(Main.this, "带图片的toast提示",
                        Toast.LENGTH_LONG);
                t.setGravity(Gravity.CENTER, 0, 0);
                View tv = t.getView();
                LinearLayout l = new LinearLayout(Main.this);
                ImageView img = new ImageView(Main.this);
                img.setImageResource(R.drawable.z1);
                l.addView(img);
                l.addView(tv);
                
                t.setView(l);
                t.show();
            }
        });

Notification 的使用：

效果：点击发送Notification，将会看到系统通知，点击，将会执行自定的操作；

代码如下：

public class Main extends Activity {

    static final int id = 0x1123;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button send = (Button) findViewById(R.id.btn1);
        Button cancel = (Button) findViewById(R.id.btn);

        send.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {

                Intent i = new Intent(Main.this, Alert.class);
                PendingIntent pi = PendingIntent
                        .getActivity(Main.this, 0, i, 0);
                Notification n = new Notification();
                n.icon = R.drawable.z1;
                n.tickerText = "启动其它通知";
                n.when = System.currentTimeMillis();
                n.defaults = Notification.DEFAULT_ALL;
                n.defaults = Notification.DEFAULT_SOUND;// 设置使用默认声音
                n.setLatestEventInfo(Main.this, "普通通知", "点击查看", pi);
                // 获取系统服务
                NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                // 发送通知
                nm.notify(id, n);
            }
        });
        cancel.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

                nm.cancel(id);
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    private void show(String s) {
        Toast.makeText(Main.this, s, Toast.LENGTH_SHORT).show();
    }
}
