Android：广播优先级、sendOrderedBroadcast、拦截、abortBroadcast、setResultData、get...
必须使用发送有序广播方法，广播优先级才有效：
|
1
2
3
4
5
6
7
8
9
10
11
12
|
findViewById(R.id.button1).setOnClickListener(
new
OnClickListener()
{
@Override
public
void
onClick(View v)
{
Intent intent =
new
Intent();
intent.setAction(
"com.example.aex56"
);
intent.putExtra(
"key"
,
"value"
);
sendOrderedBroadcast(intent,
null
);
//发送有序广播
}
});
|
