推荐答案
您可以使用BroadcastReceivers应用程序之间的通信。 在这里查看文档:
You can communicate between apps using BroadcastReceivers. Check the documentation here:
http://developer.android.com/reference/android/content/ BroadcastReceiver.html
在发送应用程序:
public void broadcastIntent(View view)
{
Intent intent = new Intent();
intent.setAction("SOME_ACTION");
intent.putExtras("key",key);
sendBroadcast(intent);
}
在接收应用程序:
public class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Intent Detected.", Toast.LENGTH_LONG).show();
String key=intent.getStringExtra("key");
// do something with the key
}
}
在接收应用程序的清单文件,在<应用>
标签:
In the manifest file of the receiving app, under <application>
tag:
<receiver android:name="MyReceiver">
<intent-filter>
<action android:name="SOME_ACTION"> <!-- Here you can use custom actions as well, research a little -->
</action>
</intent-filter>
</receiver>
