判断GPS、网络是否开启

判断GPS、网络是否开启

1.判断GPS打开与否，没有打开则打开GPS

private void initGPS(Context context) {
    LocationManager locationManager = (LocationManager) context
            .getSystemService(Context.LOCATION_SERVICE);
    // 判断GPS模块是否开启，如果没有则开启
    if (!locationManager.isProviderEnabled(android.location.LocationManager.GPS_PROVIDER)) {
        AlertDialog.Builder dialog = new AlertDialog.Builder(this);
        dialog.setMessage("请打开GPS");
        dialog.setPositiveButton("确定", new android.content.DialogInterface.OnClickListener()
                {
                    @Override
                    public void onClick(DialogInterface arg0, int arg1) {

                        // 转到手机设置界面，用户设置GPS
                        Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                        startActivityForResult(intent, 0); // 设置完成后返回到原来的界面
                    }
                });
        dialog.setNeutralButton("取消", new android.content.DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface arg0, int arg1) {
                arg0.dismiss();
            }
        });
        dialog.show();
    }
}

判断网络是否开启

private void initInternet(Context context) {
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    boolean isConnect = cm.getActiveNetworkInfo().isAvailable();
    if (!isConnect) {
        AlertDialog.Builder dialog = new AlertDialog.Builder(this);
        dialog.setMessage("请打开网络或连接wifi");
        dialog.setPositiveButton("确定", new android.content.DialogInterface.OnClickListener()
        {
            @Override
            public void onClick(DialogInterface arg0, int arg1) {

                // 转到手机设置界面，用户设置GPS
                Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                startActivityForResult(intent, 0); // 设置完成后返回到原来的界面

            }
        });
        dialog.setNeutralButton("取消", new android.content.DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface arg0, int arg1) {
                arg0.dismiss();
            }
        });
        dialog.show();
    }
}
