    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

Answer 1

No Activity found to handle Intent { 
    act=android.settings.WIFI_DISPLAY_SETTINGS 
}

onCreate    XT1706
onCreate    MobileName=XT1706
onCreate    WIFI_DISPLAY_SETTINGS is null
onCreate    android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.WIFI_DISPLAY_SETTINGS }
onCreate    XT1706
onCreate    MobileName=XT1706
onCreate    WIFI_DISPLAY_SETTINGS is null
onCreate    android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.WIFI_DISPLAY_SETTINGS }
onCreate    XT1706

Answer 2

您需要像这样使用 EXTRA_AUTHORITIES：

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

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

Answer 3

上面写着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));
