031、WiFi和GPS状态的判断及设置

根据WiFiManager可以判断WiFi状态，激活WiFi设置界面的Action为：android.provider.Settings.ACTION_WIFI_SETTINGS

通过LocationManager可以判断GPS状态，激活GPS设置界面的Action为：android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS

 

示例代码如下：

    /**
     * 检查WiFi和GPS状态
     */
    private boolean checkWifiAndGPSStatus() {
        boolean result = true;
        WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
        LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        // 判断wifi状态是否开启
        if (!wifiManager.isWifiEnabled()
                && wifiManager.getWifiState() != WifiManager.WIFI_STATE_ENABLING) {
            tv_wifi.setText("WiFi状态：未开启");
            result = false;
        } else {
            tv_wifi.setText("WiFi状态：已开启");
        }
        
        // 判断GPS状态
        if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)
                || locationManager
                        .isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
            tv_gps.setText("GPS状态：已开启");
        } else {
            tv_gps.setText("GPS状态：未开启");
            result = false;
        }
        updateConnStatus();
        return result;
    }
 
 
    /**
     * 设置WiFi
     */
    private void setWiFi() {
        Intent intent = new Intent(
                android.provider.Settings.ACTION_WIFI_SETTINGS);
        startActivityForResult(intent, 0);
    }
 
    /**
     * 设置GPS
     */
    private void setGPS() {
        Intent intent = new Intent(
                android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
        startActivityForResult(intent, 0);
    }
