推送点击处理

当点击推送时，会跳转到pendingintent指定的页面。
但是页面太多，我们想封装一个中转类，来跳转不同的Activity

public class PushTransActivity extends Activity {
    /**
     * 将类的getCanonicalName 传过来 通过反射获取Class
     */
    public static final String PUSH_TO_WHERE = "PUSH_TO_WHERE";
    public static final String PUSH_MODEL = "PUSH_MODEL";
    public static final String PUSH_ROUTER = "PUSH_ROUTER";
    public static final String PUSH_JSON = "PUSH_JSON";
    public static final String PUSH_SOURCE = "PUSH_SOURCE";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_push);


        Intent intent = getIntent();
        if (intent == null) {
            this.finish();
            return;
        }

        Bundle extras = intent.getExtras();

        Intent notifyIntent = null;
        String toWhere = intent.getStringExtra(PUSH_TO_WHERE);
        if (BuildConfig.DEBUG) {
            Logger.d("onReceive---> toWhere: %s --extras-- %s"
                    , toWhere, extras);
        }
        if (TextUtils.isEmpty(toWhere)) {
            this.finish();
            return;
        }

        try {
            Class<?> aClass = Class.forName(toWhere);
            notifyIntent = new Intent(this, aClass);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }

        if (notifyIntent != null) {
            if (extras != null) {
                notifyIntent.putExtras(extras);
            }
            startActivity(notifyIntent);
        }

        this.finish();

    }

}

PushTransActivity是透明的activity，跳转此Activity,会携带相关数据
PUSH_TO_WHERE是跳转到哪个Activity。当然，此Activity需要携带bundle的话可以支持的

Bundle extras = intent.getExtras();
notifyIntent.putExtras(extras);

有了这个中转Activity，我们就可以跳转任意Activity了
示例：

private void goLaunchPage(Context context, String msgJson, boolean showNotification, BasePushMsgEntity basePush, String source) {
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
        Intent msgIntent = new Intent(context, PushTransActivity.class);
        msgIntent.putExtra(PushTransActivity.PUSH_TO_WHERE, QueenLauncherActivity.class.getCanonicalName());
        msgIntent.putExtra(PushTransActivity.PUSH_JSON, msgJson);
        msgIntent.putExtra(PushTransActivity.PUSH_SOURCE, source);
        stackBuilder.addNextIntent(msgIntent);
        PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
        if (showNotification) {
            showNotification(context, basePush.getTitle(), basePush.getBody(), pendingIntent);
        } else {
            try {
                assert pendingIntent != null;
                pendingIntent.send();
            } catch (PendingIntent.CanceledException e) {
                e.printStackTrace();
            }
        }

    }
