<span style="font-size:18px;"><strong>private void openGPSSetting(){
		LocationManager alm = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
		if(alm.isProviderEnabled(android.location.LocationManager.GPS_PROVIDER)){
			Toast.makeText(MainActivity.this,"GPS已打开",Toast.LENGTH_SHORT).show();
		}else {
			AlertDialog.Builder dialog = new AlertDialog.Builder(MainActivity.this);
			dialog.setTitle("提示");
			dialog.setMessage("请打开GPS开关!");
			dialog.setPositiveButton("确定",new OnClickListener() {
				
				@Override
				public void onClick(DialogInterface dialog, int which) {
					// TODO Auto-generated method stub
					Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
					startActivityForResult(intent, 2111);
				}
			});
			dialog.setNegativeButton("取消", new OnClickListener() {
				
				@Override
				public void onClick(DialogInterface dialog, int which) {
					// TODO Auto-generated method stub
					dialog.dismiss();
				}
			});
			dialog.show();
		}
