Android的Notification的自定义布局按钮点击+点击按钮收回系统通知栏

一、Notification的按钮

相关代码：

	/**
	 * 显示或者刷新通知
	 */
	private void showNotification() {
		notification = new Notification();
		notification.flags = Notification.FLAG_ONGOING_EVENT;
		notification.flags |= Notification.FLAG_NO_CLEAR;
		notification.flags |= Notification.FLAG_FOREGROUND_SERVICE;
		notification.icon = R.drawable.ic_launcher;
		notification.tickerText = "点击打开应用";
		RemoteViews rv = new RemoteViews(getPackageName(), R.layout.notifi);
		String allReslut = BLTPreference.readPreference(this, ConstantPhoneInfo.SP_PREDICTION_RESULT, "");
		ArrayList<Programe> list = new ArrayList<>();
		String r[] = allReslut.split(",");
		for (int i = 0; i < r.length; i++) {
			if (!r[i].trim().equals("")) {
				Programe p = AppInfoUtil.getProgramDetailByPackageName(this, r[i].trim());
				list.add(p);
			}
		}
		Intent buttonIntent = new Intent(ACTION_BUTTON);
		if (list.size() > 0) {
			rv.setImageViewBitmap(R.id.iv1, BLTViewUtil.drawableToBitmap(list.get(0).icon));
			buttonIntent.putExtra(INTENT_BUTTONID_TAG, BUTTON_IV1_ID);
			buttonIntent.putExtra(INTENT_PACKAGE_TAG, list.get(0).packageName);
			// 这里加了广播，所及INTENT的必须用getBroadcast方法，注意第二个参数requestCode需要是不同的int值，不然会重置buttonIntent的内容
			PendingIntent intent_iv1 = PendingIntent.getBroadcast(this, 1, buttonIntent, PendingIntent.FLAG_UPDATE_CURRENT);
			rv.setOnClickPendingIntent(R.id.iv1, intent_iv1);
		}
		if (list.size() > 1) {
			rv.setImageViewBitmap(R.id.iv2, BLTViewUtil.drawableToBitmap(list.get(1).icon));
			buttonIntent.putExtra(INTENT_BUTTONID_TAG, BUTTON_IV2_ID);
			buttonIntent.putExtra(INTENT_PACKAGE_TAG, list.get(1).packageName);
			PendingIntent intent_iv2 = PendingIntent.getBroadcast(this, 2, buttonIntent, PendingIntent.FLAG_UPDATE_CURRENT);
			rv.setOnClickPendingIntent(R.id.iv2, intent_iv2);
		}
		if (list.size() > 2) {
			rv.setImageViewBitmap(R.id.iv3, BLTViewUtil.drawableToBitmap(list.get(2).icon));
			buttonIntent.putExtra(INTENT_BUTTONID_TAG, BUTTON_IV3_ID);
			buttonIntent.putExtra(INTENT_PACKAGE_TAG, list.get(2).packageName);
			PendingIntent intent_iv3 = PendingIntent.getBroadcast(this, 3, buttonIntent, PendingIntent.FLAG_UPDATE_CURRENT);
			rv.setOnClickPendingIntent(R.id.iv3, intent_iv3);
		}
		if (list.size() > 3) {
			rv.setImageViewBitmap(R.id.iv4, BLTViewUtil.drawableToBitmap(list.get(3).icon));
			buttonIntent.putExtra(INTENT_BUTTONID_TAG, BUTTON_IV4_ID);
			buttonIntent.putExtra(INTENT_PACKAGE_TAG, list.get(3).packageName);
			PendingIntent intent_iv4 = PendingIntent.getBroadcast(this, 4, buttonIntent, PendingIntent.FLAG_UPDATE_CURRENT);
			rv.setOnClickPendingIntent(R.id.iv4, intent_iv4);
		}
		notification.contentView = rv;
		if (list.size() == 0) {
			// 如果没有可预测的数据，则点击进入本应用
			rv.setViewVisibility(R.id.iv, View.VISIBLE);
			rv.setViewVisibility(R.id.ll, View.GONE);
			Intent i1 = new Intent(this, ActHome.class);
			PendingIntent contentIntent = PendingIntent.getActivity(this, 0, i1, PendingIntent.FLAG_UPDATE_CURRENT);
			notification.contentIntent = contentIntent;
		} else {
			rv.setViewVisibility(R.id.iv, View.GONE);
			rv.setViewVisibility(R.id.ll, View.VISIBLE);
		}
		this.startForeground(1, notification);
	}

	/**
	 * 初始化广播，需要在Service或者Activity开始的时候就调用
	 */
	public void initButtonReceiver() {
		bReceiver = new ButtonBroadcastReceiver();
		IntentFilter intentFilter = new IntentFilter();
		intentFilter.addAction(ACTION_BUTTON);
		registerReceiver(bReceiver, intentFilter);
	}

	public ButtonBroadcastReceiver bReceiver;
	public final static String ACTION_BUTTON = "com.notifications.intent.action.ButtonClick";
	public final static String INTENT_BUTTONID_TAG = "ButtonId";
	public final static String INTENT_PACKAGE_TAG = "packageName";
	public final static int BUTTON_IV1_ID = 1;
	public final static int BUTTON_IV2_ID = 2;
	public final static int BUTTON_IV3_ID = 3;
	public final static int BUTTON_IV4_ID = 4;

	/**
	 * 按钮点击广播
	 * 
	 */
	public class ButtonBroadcastReceiver extends BroadcastReceiver {

		@Override
		public void onReceive(Context context, Intent intent) {
			String action = intent.getAction();
			if (action.equals(ACTION_BUTTON)) {
				collapseStatusBar(ServiceProcess.this);
				Intent i1 = new Intent();
				int buttonId = intent.getIntExtra(INTENT_BUTTONID_TAG, 0);
				String packageName = intent.getStringExtra(INTENT_PACKAGE_TAG);
				System.out.println(packageName + "   " + buttonId);
				PackageManager packageManager = ServiceProcess.this.getPackageManager();
				i1 = packageManager.getLaunchIntentForPackage(packageName);
				i1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED | Intent.FLAG_ACTIVITY_CLEAR_TOP);
				ServiceProcess.this.startActivity(i1);
				// // 对不同的按钮做不同的事情
				// switch (buttonId) {
				// case BUTTON_IV1_ID:
				// BLTLog.v("BUTTON_IV1_ID", "BUTTON_IV1_ID");
				//
				// break;
				// }
			}
		}
	}

	/**
	 * 关闭下拉通知栏
	 * 
	 * 需要添加权限：<uses-permission android:name="android.permission.EXPAND_STATUS_BAR" />
	 * 
	 * @param context
	 */
	public static void collapseStatusBar(Context context) {
		try {
			Object statusBarManager = context.getSystemService("statusbar");
			Method collapse;
			if (Build.VERSION.SDK_INT <= 16) {
				collapse = statusBarManager.getClass().getMethod("collapse");
			} else {
				collapse = statusBarManager.getClass().getMethod("collapsePanels");
			}
			collapse.invoke(statusBarManager);
		} catch (Exception localException) {
			localException.printStackTrace();
		}
	}

二、点击按钮收回系统通知栏

注意：需要在Manifest中添加权限：

<uses-permission android:name="android.permission.EXPAND_STATUS_BAR" />

代码如下：使用反射

/**
	 * 关闭下拉通知栏
	 * 
	 * 需要添加权限：<uses-permission android:name="android.permission.EXPAND_STATUS_BAR" />
	 * 
	 * @param context
	 */
	public static void collapseStatusBar(Context context) {
		try {
			Object statusBarManager = context.getSystemService("statusbar");
			Method collapse;
			if (Build.VERSION.SDK_INT <= 16) {
				collapse = statusBarManager.getClass().getMethod("collapse");
			} else {
				collapse = statusBarManager.getClass().getMethod("collapsePanels");
			}
			collapse.invoke(statusBarManager);
		} catch (Exception localException) {
			localException.printStackTrace();
		}
	}
