Android的：不能内螺纹已不叫尺蠖prepare创造处理器（） [英] Android: Can't create handler inside thread that has not called Looper.prepare()
本文介绍了Android的：不能内螺纹已不叫尺蠖prepare创造处理器（）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图运行下面的，但我得到的错误
无法创建内螺纹的处理程序已经不叫活套。prepare（）
下面是我的code
私有静态无效的getLocations（）{ 尝试{ m_locationManager =（的LocationManager）activity.getSystemService（Context.LOCATION_SERVICE）;
m_locationListener =新LocationListener的（）{
公共无效onLocationChanged（地点）{Log.d（输出，onLocationChanged）;}
公共无效onStatusChanged（字符串提供商，INT地位，捆绑演员）{Log.d（输出，onStatusChanged）;}
公共无效onProviderEnabled（字符串提供商）{Log.d（输出，onProviderEnabled）;}
公共无效onProviderDisabled（字符串提供商）{Log.d（输出，onProviderDisabled）;}
};
m_locationManager.requestLocationUpdates（LocationManager.NETWORK_PROVIDER，1000，1000，m_locationListener）; Log.d（输出，完成）; }赶上（例外前）{
Log.d（输出，ex.getMessage（））;
} }
如果我把活套。prepare（）的requestLocationUpdates（）之前的错误消失，但没有事件被解雇
如果我再放入Looper.loop（）在该requestLocationUpdates（）之后，它会暂停和完成日志不会被调用。
如果调用是否在runOnUiThread的功能，像这样：
activity.runOnUiThread（新的Runnable（）{
公共无效的run（）{的getLocations（）; }
}）;
没有事件被解雇了。
进出口运行以此为Unity游戏引擎的插件，所以我不必在主线程直接访问。
我曾尝试运行此code Untiy之外，它运行正常。
林pretty停留在这一个，所以任何帮助将是AP preciated。
干杯
更新：
所以我现在正试图获取一个单独的活动里面的位置。然而，事件还没有被调用。
公共类LocationActivity扩展活动实现LocationListener的{ 私人的LocationManager m_locationManager; 公共无效的onCreate（捆绑savedInstanceState）{ super.onCreate（savedInstanceState）; 内容的LinearLayout =新的LinearLayout（本）;
content.setLayoutParams（新的LayoutParams（LayoutParams.FILL_PARENT，LayoutParams.FILL_PARENT））;
content.setOrientation（LinearLayout.VERTICAL）;
content.setBackgroundColor（Color.TRANSPARENT）; TextView的infoLabel =新的TextView（本）;
infoLabel.setLayoutParams（新LinearLayout.LayoutParams（LayoutParams.FILL_PARENT，LayoutParams.WRAP_CONTENT））;
infoLabel.setTextSize（20.0f）;
infoLabel.setText（初始化...）;
content.addView（infoLabel）; 尝试{
m_locationManager =（的LocationManager）getSystemService（Context.LOCATION_SERVICE）; 字符串提供商= NULL; 如果（m_locationManager.isProviderEnabled（LocationManager.GPS_PROVIDER））{
供应商= LocationManager.GPS_PROVIDER;
Log.d（团结，使用GPS）;
m_locationManager.requestLocationUpdates（供应商，1000，100，这一点）;
}否则如果（m_locationManager.isProviderEnabled（LocationManager.NETWORK_PROVIDER））{
供应商= LocationManager.NETWORK_PROVIDER;
Log.d（团结，使用Netword）;
m_locationManager.requestLocationUpdates（供应商，1000，100，这一点）;
}其他{
Log.d（团结，提供者不可用）;
} }赶上（例外前）{
Log.d（团结，locatons错误+ ex.getMessage（））;
} 的setContentView（内容）; } 公共无效onLocationChanged（地点）{
Log.d（团结，UserLocation纬度：+ location.getLatitude（）+长：+ location.getLongitude（））;
}
公共无效onStatusChanged（字符串提供商，INT地位，捆绑演员）{Log.d（团结，onStatusChanged）;}
公共无效onProviderEnabled（字符串提供商）{Log.d（团结，onProviderEnabled）;}
公共无效onProviderDisabled（字符串提供商）{Log.d（团结，onProviderDisabled）;}
}
该视图被正确打开，以及GPS和网络可用。仍然没有触发事件
使用林这些权限
＆LT;使用许可权的android：NAME =android.permission.ACCESS_WIFI_STATE/＆GT;
＆LT;使用许可权的android：NAME =android.permission.ACCESS_COARSE_LOCATION/＆GT;
＆LT;使用许可权的android：NAME =android.permission.ACCESS_FINE_LOCATION/＆GT;

＆LT;使用许可权的android：NAME =android.permission.READ_PHONE_STATE/＆GT;
＆LT;使用许可权的android：NAME =android.permission.INTERNET对/＆GT;
解决方案
尝试 mView.post（新的Runnable（）{的getLocations（）};
I am trying to run the following but am getting the error
Can't create handler inside thread that has not called Looper.prepare()
Here is my code
private static void getLocations(){
try{
m_locationManager = (LocationManager) activity.getSystemService(Context.LOCATION_SERVICE);
m_locationListener = new LocationListener() {
public void onLocationChanged(Location location) {Log.d("Output", "onLocationChanged");}
public void onStatusChanged(String provider, int status, Bundle extras) {Log.d("Output", "onStatusChanged");}
public void onProviderEnabled(String provider) {Log.d("Output", "onProviderEnabled");}
public void onProviderDisabled(String provider) {Log.d("Output", "onProviderDisabled");}
};
m_locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1000, 1000, m_locationListener);
Log.d("Output", "done");
}catch(Exception ex){
Log.d("Output", ex.getMessage());
}
}
If i put Looper.prepare() before the requestLocationUpdates() the error goes away but no events are fired
If i then put Looper.loop() after the the requestLocationUpdates() it pauses and the "done" log is not called.
If if call the function within runOnUiThread like so:
activity.runOnUiThread(new Runnable() {
public void run() {getLocations(); }
});
no events are fired.
Im running this as a plugin for the Unity game engine so i don't have direct access to the main thread.
I have tried running this code outside of Untiy and it runs fine.
Im pretty stuck on this one so any help would be appreciated.
Cheers
Update:
So i'm now trying to retrieve the locations inside a separate Activity. However, the events are still not being called.
public class LocationActivity extends Activity implements LocationListener{
private LocationManager m_locationManager;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout content = new LinearLayout(this);
content.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
content.setOrientation(LinearLayout.VERTICAL);
content.setBackgroundColor(Color.TRANSPARENT);
TextView infoLabel = new TextView(this);
infoLabel.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
infoLabel.setTextSize(20.0f);
infoLabel.setText("Initializing...");
content.addView(infoLabel);
try{
m_locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
String provider = null;
if ( m_locationManager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
provider = LocationManager.GPS_PROVIDER ;
Log.d("Unity", "Using GPS");
m_locationManager.requestLocationUpdates(provider, 1000, 100, this);
} else if(m_locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
provider = LocationManager.NETWORK_PROVIDER;
Log.d("Unity", "Using Netword");
m_locationManager.requestLocationUpdates(provider, 1000, 100, this);
} else {
Log.d("Unity", "Provider Not available");
}
}catch(Exception ex){
Log.d("Unity", "locatons error " + ex.getMessage());
}
setContentView(content);
}
public void onLocationChanged(Location location) {
Log.d("Unity", "UserLocation Lat:" + location.getLatitude() + " Long:" + location.getLongitude());
}
public void onStatusChanged(String provider, int status, Bundle extras) {Log.d("Unity", "onStatusChanged");}
public void onProviderEnabled(String provider) {Log.d("Unity", "onProviderEnabled");}
public void onProviderDisabled(String provider) {Log.d("Unity", "onProviderDisabled");}
}
The view is opened correctly and and Both GPS and Network are available. Still no firing events
Im using these permissions
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_GPS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>
解决方案
Try mView.post(new Runnable() { getLocations() };
