Android使用Notification实现宽视图通知栏（二）

public class MainActivity extends AppCompatActivity {
  private static final int NO_2 =0x2;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
  }
  //按钮的点击方法
  public void show(View v){
    NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
    builder.setSmallIcon(R.mipmap.guojia);
    builder.setContentTitle("郭嘉");//系统限制，可能不显示
    builder.setContentText("我们打袁绍吧");//系统限制，可能不显示
    builder.setDefaults(Notification.DEFAULT_ALL);
    //添加宽视图
    NotificationCompat.InboxStyle style = new NotificationCompat.InboxStyle();
    style.setBigContentTitle("十胜十败");
    //由手机屏幕像素决定显示多少
    style.addLine("第一是道胜");
    style.addLine("第二是义胜");
    style.addLine("第三是治胜");
    style.addLine("第四是度胜");
    style.addLine("第五是谋胜");
    style.addLine("第六是德胜");
    style.addLine("第七是仁胜");
    style.addLine("第八是明胜");
    style.addLine("第九是文胜");
    style.addLine("第十是武胜");
    style.setSummaryText("作者：郭嘉");//添加概要
    builder.setStyle(style);
    Notification n = builder.build();
    NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(NO_2, n);
  }
}
