同一意图的小部件上的多个 OnClick
我的小部件启动一个服务,并且该服务更新 3 个 LinearLayout 的列表。
我想在每个 LinearLayout 上设置一个带有不同 Extra 的 SetOnClickPeningIntent
但当我启动小部件并想要单击 LinearLayouts 时,只有最后一个是 onclickable =/ 我不知道出了什么问题。希望你能帮助我。
RemoteViews remoteViews = new RemoteViews(getPackageName(),
R.layout.widget_layout);
for (int widgetId : appWidgetIds) {
int[] lls = { R.id.ll_con_1, R.id.ll_con_2, R.id.ll_con_3 };
for (int i = 0; i < jray.length(); i++) {
try {
JSONObject o = jray.getJSONObject(i);
//Onclick
if(i == 0)
{
Intent msg_intent = new Intent(getApplicationContext(), MSGsOpenMsg.class);
msg_intent.putExtra("messageid", o.getString("id"));
PendingIntent msg_pendingIntent = PendingIntent.getActivity(
getApplicationContext(), 0, msg_intent, Intent.FLAG_ACTIVITY_NEW_TASK);
remoteViews.setOnClickPendingIntent(R.id.ll_con_1, msg_pendingIntent);
}
else if(i == 1)
{
Intent msg_intent1 = new Intent(getApplicationContext(), MSGsOpenMsg.class);
msg_intent1.putExtra("messageid", o.getString("id"));
PendingIntent msg1_pendingIntent = PendingIntent.getActivity(
getApplicationContext(), 0, msg_intent1, Intent.FLAG_ACTIVITY_NEW_TASK);
remoteViews.setOnClickPendingIntent(R.id.ll_con_2, msg1_pendingIntent);
}
else if(i == 2)
{
Intent msg_intent = new Intent(getApplicationContext(), MSGsOpenMsg.class);
msg_intent.putExtra("messageid", o.getString("id"));
PendingIntent msg2_pendingIntent = PendingIntent.getActivity(
getApplicationContext(), 0, msg_intent, Intent.FLAG_ACTIVITY_NEW_TASK);
remoteViews.setOnClickPendingIntent(R.id.ll_con_3, msg2_pendingIntent);
}
} catch (JSONException e) {
}
}
}
My Widget starts a Service and the Service Update a List of 3 LinearLayouts.
I want to set on each LinearLayout a SetOnClickPeningIntent with different Extra
But when i start the widget and want to click on the LinearLayouts only the last one is onclickable =/ I dont know what's wrong. Hope you can help me.

我遇到过这个问题。这是因为 Android 试图将类似的 PendingIntents 折叠成 1 个,这会产生一些非常烦人的后果。 IE 中,当旧的意图有细微的不同时,它们就会被丢弃。我认为它们的折叠方式也存在一个错误,因为它与文档不匹配。 (我很久以前就遇到过这个问题,所以事情可能已经改变了。)
基本上我确保 PendingIntent.getActivity 是每个 UI 项目都不同。这样他们每个人都会得到自己的 PendingIntent 并且永远不会发生冲突。
我这里有代码试图解决这个问题,但这有点浪费。

我会承认我的解决方案代码不是最好的,但到目前为止似乎运行得很好。
I've had this problem. It's because Android tries to collapse similar PendingIntents into 1 one and this has some really annoying consequences. IE the older intents are dropped when they are subtly different. I think there's also a bug in how they do collapsing as well since it doesn't match the documentation. (I ran into this a long time ago so things could have changed.)
Basically I make sure that the requestCode parameter in PendingIntent.getActivity is different for each UI item. That way they each get their own PendingIntent and never collide.
I have code here that tries to get around the problem but it's a bit wasteful.

I will admit the solution in my code isn't the best but it seems to work pretty well so far.
