我正在尝试使用 Parcelable 将我的 BroadcastReceiverListener 类中的一些数据传递到 MainActivity 类中的 onNewIntent() 但我收到此错误“找不到处理 Intent 的 Activity { act=android.net.wifi.SCAN_RESULTS flg=0x4000010 }”
BroadcastReceiverListener 类:
public class BroadcastReceiverListener extends BroadcastReceiver implements Parcelable {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(
android.net.wifi.WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)) {
WifiManager wifiManager = (WifiManager) context
.getSystemService(Context.WIFI_SERVICE);
final List<ScanResult> results = wifiManager.getScanResults();
if (results != null) {
ArrayList<ScanResult> updatedResults = new ArrayList<ScanResult>();
for (int i = 0; i < results.size(); i++) {
String ssid = results.get(i).SSID;
if (ssid.startsWith("KD")) {
updatedResults.add(results.get(i));
}
}
Intent updateIntenet = new Intent(context, MainActivity.class);
updateIntenet.putParcelableArrayListExtra("broadcast_event",
updatedResults);
context.startActivity(intent);
}
}
else if (intent.getAction().equals(
android.net.ConnectivityManager.CONNECTIVITY_ACTION)) {
}
}
}
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
// TODO Auto-generated method stub
}
}
MainActivity 中的 onNewIntent 方法:
@Override
protected void onNewIntent(Intent intent) {
String intentResult = intent.getStringExtra("broadcast_event");
if (intentResult != null) {
List<ScanResult> results = intent.getParcelableArrayListExtra("broadcast_event");
String a = deliverBestAccessPoint(results);
textWifi.setText(a.toString());
} else {
textWifi.setText("No route is available.");
}
}
list :
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".BroadcastReceiverListener" >
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
<action android:name="android.net.wifi.SCAN_RESULTS" />
</intent-filter>
</receiver>
</application>
最佳答案
您正在调用 startActivity(intent)。据推测，根据您的代码，您希望调用 startActivity(updateIntenet)。
