我想将一个活动的简单sata发送到另一个活动。两者都处于活动状态,并且我已经注册了LocalBroadcastManager。发送部分工作,但接收活动却什么都没有。 BroadcastManager发送数据的部分代码:
myButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
LocalBroadcastManager broadcaster = LocalBroadcastManager.getInstance(SendingDataPageActivity.this);
Intent broadcastIntent = new Intent(BROADCAST_INTENT);
broadcastIntent.putExtra("test, "test");
broadcastIntent.setAction("test, "test");
broadcaster.sendBroadcast(broadcastIntent);
Log.d(TAG, "Broadcast sent..."); });
对于接收者:
public class RecievingDataPageActivity extends AppCompatActivity{
BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Log.d(TAG, "local broadcaster received...");}};
我已经在OnCreate中注册了它:
LocalBroadcastManager.getInstance(this).registerReceiver((receiver),
new IntentFilter(BROADCAST_INTENT));
但是仍然没有收到任何东西。有帮助吗?

删除此行,然后重试。
broadcastIntent.setAction(“ test,” test“);

您正在Intent构造函数中设置操作:
broadcastIntent.setAction("test", "test");
但是两行之后,您将其覆盖:
with open('test.py') as f:
print(f.readlines())
您只能执行一项操作,否则Intent将会丢失。
