我浪费了很多时间试图查找为什么这个alertDialog没有显示在我的其他状态，但是这里的IF语句是我的代码。
if (locManager.isProviderEnabled(LocationManager.GPS_PROVIDER) && locManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){
setupMapIfRequired();
}else{
Log.d("turn on location Services", "turn on gps " + "a" + ": " + "aa");
Toast.makeText(this, "Please turn on gps provider location services...................", 1000).show();
startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
showDialog();
}
任何人都可以帮助我吗？注意 。这只是我代码上的问题区域所以我只发布了这个部分。如果我放置showDialog（）;代码可以工作;在IF语句中，但它在我调用位置服务设置的else部分不起作用。
这里是showDialog（）;功能
private void showDialog() {
// TODO Auto-generated method stub
AlertDialog.Builder ab = new AlertDialog.Builder(this);
ab.setTitle("Hello!!");
ab.setMessage("ALL ARE EQUAL");
ab.setCancelable(false);
ab.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
});
AlertDialog ad = ab.create();
ad.show();
}
这里是logcat
