当我的应用程序在Android中运行时，如何打开Wifi？

Question

当我启动我的Twitter应用程序时，如何通过编码自动打开WiFi？

Answer 1

I have not tried this but it should work:

WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
if (wifiManager != null)
  wifiManager.setWifiEnabled(true);

Add this permission to the manifest file:

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

if (text.indexOf("off") != -1) { WifiManager wifi = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE); if (!wifi.isWifiEnabled()) { Toast.makeText(MainActivity.this, "Already WiFi is Disabled", Toast.LENGTH_SHORT).show(); tts.speak("Already WiFi is Disabled", TextToSpeech.QUEUE_ADD, null); } else { wifi.setWifiEnabled(false); Toast.makeText(MainActivity.this, "Turning off wifi"Toast.LENGTH_SHORT).show(); tts.speak("Turning off wifi", TextToSpeech.QUEUE_ADD, null); } }

  if (text.indexOf("wi-fi") != -1) {
            if (text.indexOf("on") != -1) {
                WifiManager wifi = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
                if (wifi.isWifiEnabled()) {
                    Toast.makeText(MainActivity.this, "Already WiFi is Enabled", Toast.LENGTH_SHORT).show();
                    tts.speak("Already WiFi is Enabled", TextToSpeech.QUEUE_ADD, null);
                }
          else {
                wifi.setWifiEnabled(true);
                Toast.makeText(MainActivity.this,"Turning on",Toast.LENGTH_SHORT).show();
                Toast.makeText(MainActivity.this, "Turning on wifi", Toast.LENGTH_SHORT).show();
                tts.speak("Turning on wifi", TextToSpeech.QUEUE_ADD, null);
            }
        }
