android GPS启用按钮点击

Question

这是我的代码。 （它使alertdialog移动设置） 但我只想启用GPS时，我“启用GPS”按钮单击。 和安卓总是启用按钮点击时，我运行的应用程序不只是运行一次？

AlertDialog.Builder builder = new AlertDialog.Builder(this); 
builder.setMessage("Your GPS is disabled! Would you like to enable it?") 
.setCancelable(false) 
.setPositiveButton("Enable GPS", 
new DialogInterface.OnClickListener() { 
    public void onClick(DialogInterface dialog, int id) { 
     moveConfigGPS(); 
    } 
}).setNegativeButton("Do nothing", 
new DialogInterface.OnClickListener() { 
    public void onClick(DialogInterface dialog, int id) { 
     dialog.cancel(); 
    } 
}); 

AlertDialog alert = builder.create(); 
alert.show(); 

Answer 1

我想你想与点击像谷歌开启GPS定位做。

要提示允许修改位置设置的用户，呼叫startResolutionForResult（活动，INT）。此方法会弹出一个对话框，询问用户是否有权修改位置设置。 This link shows how to check the location settings, and how to call startResolutionForResult(Activity, int).

Answer 2

你不能只启用GPS，你可以用这个意图只开GPS设置：

Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); 
startActivity(intent); 

Answer 3

User these method to on GPS : 

    intent1 = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); 
    startActivity(intent1); 

and add these method to check GPS is on or Off ?? 
public void CheckGpsStatus(){ 

locationManager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE); 

GpsStatus = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER); 

if(GpsStatus == true) 
{ 
textview.setText("Location Services Is Enabled"); 
}else { 
textview.setText("Location Services Is Disabled"); 
} 

}
