我正在尝试调用显示 WiFi、声音和蓝牙但不起作用的设置：我将把我的代码和 logcat

我想在这里使用看图片在此处输入图像描述 

 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    setContentView(R.layout.wifi);

    Button wifi =(Button)findViewById(R.id.wifi);
    wifi.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {


            Intent intent = new Intent(android.provider.Settings.AUTHORITY);
            intent.putExtra(Settings.EXTRA_AUTHORITIES, new String[] {                      

                    android.provider.Settings.ACTION_BLUETOOTH_SETTINGS
                                });
            intent.putExtra(Settings.EXTRA_AUTHORITIES, new String[] {                      

                    android.provider.Settings.ACTION_WIFI_SETTINGS
                                });
            startActivity(intent);
        }
    });
}

您需要像这样使用 EXTRA_AUTHORITIES：

intent.putExtra(Settings.EXTRA_AUTHORITIES, new String[] {
    Calendar.AUTHORITY
});

并且 intent.addCategory 不用于此。仅使用一个 android.provider.Settings。按意图键入。

它在说ActivityNotFound。所以问题一定出在这一行。

Intent intent = new Intent(android.provider.Settings.EXTRA_AUTHORITIES);

我觉得你应该试试

startActivity(new Intent(Settings.ACTION_SETTINGS));
