问题描述
我想两项活动是标签内部之间传递数据。我试图用sendBroadcast。断点设置我永远达不到的onReceive。
清单:
<活动机器人:WebResultsNAME =
机器人:标签=@字符串/ APP_NAME>
<意向滤光器>
<作用机器人:名称=com.toxy.LOAD_URL/>
&所述; /意图滤光器>
< /活性GT;
活动发件人:
意向意图=新的意图(getApplicationContext(),WebResults.class);
intent.setAction(com.toxy.LOAD_URL);
intent.putExtra(URL,uri.toString());
sendBroadcast(意向);
活动Reciever:
@覆盖
公共无效的onCreate(包savedInstanceState){
super.onCreate(savedInstanceState);
IntentFilter的过滤器=新的IntentFilter(com.toxy.LOAD_URL);
this.registerReceiver(新的接收器(),过滤器);
}
私有类接收器扩展的BroadcastReceiver {
@覆盖
公共无效的onReceive(背景为arg0,意图ARG1){
字符串URL = arg1.getExtras()的getString(URL)。
的WebView的WebView =(web视图)findViewById(R.id.webView);
webview.loadUrl(URL);
}
}
解决方案
我有同样的问题,因为你,但我想通了:
从清单中删除的意图过滤器,并更改
意向意图=新的意图(getApplicationContext(),WebResults.class);
为
意向意图=新的意图();
希望它能帮助!
I am trying to pass data between two activities that are inside of tabs. I am trying to use the sendBroadcast. With breakpoints set I never reach the OnReceive.
manifest :
<activity android:name=".WebResults"
android:label="@string/app_name">
<intent-filter>
<action android:name="com.toxy.LOAD_URL" />
</intent-filter>
</activity>
Activity Sender:
Intent intent=new Intent(getApplicationContext(),WebResults.class);
intent.setAction("com.toxy.LOAD_URL");
intent.putExtra("url",uri.toString());
sendBroadcast(intent);
Activity Reciever :
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
IntentFilter filter = new IntentFilter("com.toxy.LOAD_URL");
this.registerReceiver(new Receiver(), filter);
}
private class Receiver extends BroadcastReceiver {
@Override
public void onReceive(Context arg0, Intent arg1) {
String url = arg1.getExtras().getString("url");
WebView webview =(WebView)findViewById(R.id.webView);
webview.loadUrl(url);
}
}
解决方案
I was having the same problem as you, but I figured out:
Remove the intent filter from the manifest and change
Intent intent=new Intent(getApplicationContext(),WebResults.class);
for
Intent intent=new Intent();
Hope it helps!
