android Intent 不适用于 wifi、声音、蓝牙？

Question

我尝试调用显示 WiFi、声音和蓝牙但不起作用的设置:我将把我的代码放在这里，还有 logcat 我想在按钮单击事件上设置此设置并仅显示选定的图标如果有任何其他方式使用它

我想像这里看图片一样使用

 @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);
        }
    });
}

Logcat

Answer 1

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 Intent 输入。
