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

我没有尝试过，但它应该有效：

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

将此权限添加到清单文件中：

<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（“已经禁用WiFi”，TextToSpeech.QUEUE_ADD，null）; } else {wifi.setWifiEnabled（false）; Toast.makeText（MainActivity.this，“关闭wifi”Toast.LENGTH_SHORT）.show（）; tts.speak（“关闭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);
            }
        }

当我的应用程序在Android中运行时，如何打开Wifi？
