需求：

我想要实现的 UI给的效果图

代码删掉没有提交，现在写不回去了。不过反正都没有满足需求。

/1/ 这个是我获取到并且过滤剩的wifi信息。有两个item项。

/2/现在我需要点击，弹出输入密码框。红框部分是获取点击的wifi name。这个点击获取到的没有问题。

点击的代码：

    @Override
    protected void initListener() {
        //ITEM项的点击事件
        mNoConnectListAdapter.setOnItemClickListener(new DeviceNoConnectListAdapter.OnItemClickListener() {
            @Override
            public void onItemClick(int position) {
                mCurrentPos = position; //获取当前点击的pos
                WifiManager wifiManager = (WifiManager) requireContext().getApplicationContext().getSystemService(Context.WIFI_SERVICE);
                if (wifiManager != null && wifiManager.isWifiEnabled()) {
                    Router router = sRouterList.get(mCurrentPos);
//                    Logger.d(TAG,"position -- ?> " + position + " item name -- > "+ router.getName());
//                    NLMeshToast.getInstance(getContext()).showShortToast("position --- > " + position + "router name -- > " + router.getName());
                    noConfigurationWifi(mCurrentPos);  //需要密码，弹出输入密码的Dialog
                }else {
                    intentToOpenWifiService(); //跳转到打开wifi的系统设置界面
                }
            }
        });
    }

/3/

执行这一方法：noConfigurationWifi(mCurrentPos)

/**
 * 之前没配置过该网络， 弹出输入密码界面
 * @param position
 */
private void noConfigurationWifi(int position) {
    Logger.d(TAG,"current click pos" + position);
    NLMeshToast.getInstance(getContext()).showShortToast("current click pos " + position);
    WifiLinkDialogFragment wifiLinkDialogFragment = new WifiLinkDialogFragment();
    wifiLinkDialogFragment.getData(mScanResultArrayList.get(position));
    wifiLinkDialogFragment.show(getChildFragmentManager(),"");
}

我用的是DialogFragment 实现输入框

输入框显示后，输入完点击YES按钮。

这里的点击事件代码如下：

mConfirmBtn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if(mPasswordEt.getText().toString().length() < 8){
            return;
        }else {
            //实现wifi连接
            NLMeshToast.getInstance(getContext()).showShortToast("click yes btn");
            WifiSupport.WifiCipherType wifiCipher = WifiSupport.getWifiCipher(mCapabilities);
            WifiConfiguration config = WifiSupport.createWifiConfig(mItem.SSID, mInputPassword, wifiCipher);
            boolean result = WifiSupport.addNetWork(config, requireContext());  //连接指定wifi，返回连接wifi的结果
            Logger.d(TAG,"wifi connect result --- > " + result);
            dismiss(); //关闭输入框
        }

    }
});
mCancelBtn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //关闭输入框
        dismiss();
    }
});

我的广播接收者代码： -- 网上例程改的。

public static class WifiBroadcastReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        if(WifiManager.WIFI_STATE_CHANGED_ACTION.equals(intent.getAction())){
            int state = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, 0);
            switch (state){
                /**
                 * WIFI_STATE_DISABLED    WLAN已经关闭
                 * WIFI_STATE_DISABLING   WLAN正在关闭
                 * WIFI_STATE_ENABLED     WLAN已经打开
                 * WIFI_STATE_ENABLING    WLAN正在打开
                 * WIFI_STATE_UNKNOWN     未知
                 */
                case WifiManager.WIFI_STATE_DISABLED:{
                    Log.d(TAG,"wifi disable");
                    NLMeshToast.getInstance(NLApplication.getContext()).showShortToast("wifi disable");
                    break;
                }
                case WifiManager.WIFI_STATE_DISABLING:{
                    Log.d(TAG,"wifi disabling");
                    break;
                }
                case WifiManager.WIFI_STATE_ENABLED:{
                    Log.d(TAG,"wifi enabled");
                    break;
                }
                case WifiManager.WIFI_STATE_ENABLING:{
                    Log.d(TAG,"wifi enabling");
                    break;
                }
                case WifiManager.WIFI_STATE_UNKNOWN:{
                    Log.d(TAG,"unknown state");
                    break;
                }
            }
        }else if(WifiManager.NETWORK_STATE_CHANGED_ACTION.equals(intent.getAction())){
                NetworkInfo info = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
                Log.d(TAG, "--NetworkInfo--" + info.toString());
            if(NetworkInfo.State.DISCONNECTED == info.getState()){//wifi没连接上
                Log.d(TAG,"wifi connect error");
                mNoConnectListAdapter.notifyDataSetChanged();
            }else if(NetworkInfo.State.CONNECTED == info.getState()) {//wifi连接上了
                Log.d(TAG, "wifi connected");
                NLMeshToast.getInstance(NLApplication.getContext()).showShortToast("wifi connected");
            }else if(NetworkInfo.State.CONNECTING == info.getState()){
                Log.d(TAG,"wifi connecting");;
            }
        }else if(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION.equals(intent.getAction())){
                Log.d(TAG,"network list change");
        }
    }

}

这部分的代码大致是这样了。

在广播接受者 中根据接收到的wifi状态修改UI，出现以下问题：

（1 ）点击NL-2,4g的item

（2）

点击wlan 5g的，输入完 在连接过程中，更新的也是NL2.4的item ui，成功后修改的也是2,4g的ui。

跟上面的图一样。

===================================

private void wifiListSet(String ssid,String state) {
    int sIndex = -1;
    Router router = new Router();
    for (int i = 0; i < sRouterList.size(); i++) {
        Router wifiInfo = sRouterList.get(i);
        if(sIndex == -1 && ("\"" + wifiInfo.getName() + "\"").equals(ssid)){
            Logger.d(TAG,"wifi info --");
            sIndex = i;
            router.setState(state);
            router.setName(wifiInfo.getName());
            router.setMac(wifiInfo.getMac());
        }

    }
    if(sIndex != -1){
        sRouterList.remove(sIndex);
        sRouterList.add(sIndex,router);
        mNoConnectListAdapter.setRouterData(sRouterList);
        mNoConnectListAdapter.notifyDataSetChanged();
    }

}

如果有完美实现的思路，麻烦大伙们底下评论轰炸我。边写android代码还得边算硬件加工的成本还得搞其他杂活，自己写的代码太差了。冲冲冲！！！
