按钮点击时启用Android GPS

Question

这是我的代码。 （它使alertdialog移动设置） 但我只是想在启动GPS时启用GPS＆＃34;启用GPS＆＃34;按钮单击。 当我运行app而不只是运行一次时，android总是启用按钮点击吗？

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

您无法启用GPS，您只能使用此意图打开gps设置：

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

Answer 2

    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"); 
 }

 }

我认为您只需点击Google就可以打开GPS位置。

要提示用户修改位置设置的权限，请调用startResolutionForResult（Activity，int）。此方法会显示一个对话框，要求用户修改位置设置。 This link shows how to check the location settings, and how to call startResolutionForResult(Activity, int).
