我正在尝试创建一个显示类似ACTION_PICK_WIFI_NETWORK的对话框,但不是打开 Android设置/ WiFi而是在对话框上打开它,如果可能的话,用户可以连接到该对话框中可用的任何网络.我目前正在打开一个带有Android中可用Wi-Fi网络列表的Dialog,但这个列表与Android设置/ WiFi不同,这就是为什么我要问是否可以打开此ACTION_PICK_WIFI_NETWORK一个对话框并使用它.如果不可能我如何连接到网络点击我的对话框中的项目与WiFi可用？

到目前为止我尝试过的是

我有一个broadcastReceiver()

wifiReceiver = new broadcastReceiver(){
@Override
  public void onReceive(Context c,Intent intent){  
       if(mWifiManager != null) {
          List<ScanResult> results = mWifiManager.getScanResults();
          showWifiListDialog(results);
       }
  }
};

RegisterReceiver()

registerReceiver(wifiReceiver,new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));

这是WifiScan的方法

private void startWifiScans() {
 mWifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
 mWifiManager.startScan();
}

这是一个简单的Dialog,它显示了SCAN_RESULTS_AVAILABLE_ACTION

private void showWifiListDialog(List<ScanResult> results) {
    AlertDialog.Builder builderSingle = new AlertDialog.Builder(
            this);
    final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
            this,android.R.layout.select_dialog_item);

    for (ScanResult r: results) {
        if(r == null || r.SSID == null) continue;
        if("".equalsIgnoreCase(r.SSID.trim())) continue;
        String name = r.SSID.replace("\"","");
        arrayAdapter.add(name);
    }
    builderSingle.setNegativeButton(getString(R.string.cancel),new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog,int which) {
                    dialog.dismiss();
                }
            });
    builderSingle.setAdapter(arrayAdapter,int which) {
                    String strName = arrayAdapter.getItem(which);
                    Toast.makeText(getApplicationContext(),"Selected "+strName,Toast.LENGTH_SHORT).show();
                }
            });
    AlertDialog dialog = builderSingle.create();
    dialog.show();
}

图像示例

This和this是我正在寻找的例子.

编辑(这是我现在看到我的对话但是我不喜欢它……)

我想用带有信号强度的图标向网络显示像android一样的example.我想我需要一个listadapter左右？然后添加网络名称,强度连接,图标等…我错了吗？

对there几乎同样的问题..

我想通过通知打开它,显然无论我是在那个APP还是其他APP上都没关系…我只想打开它作为一个对话框,让用户看看用户在看什么.

现在我得到的是：

我正在使用主题,但它没有做我想要的.

<style name="dialogtest" parent="AppTheme">
    <item name="android:windowFrame">@android:color/transparent</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="android:windowBackground">@android:color/transparent</item>
</style>

这是风格,我称之为：

protected void onCreate(Bundle savedInstanceState) {
    setTheme(R.style.dialogtest);
    super.onCreate(savedInstanceState);

从ui的角度来看,您需要一个自定义适配器：

private class WifiAdapter extends ArrayAdapter<ScanResult> {

    public WifiAdapter(Context context,int resource,List<ScanResult> objects) {
        super(context,resource,objects);
    }

    @Override
    public View getView(int position,View convertView,ViewGroup parent) {
        if (convertView == null) {
            convertView = getLayoutInflater().inflate(R.layout.wifi_item,parent,false);
        }
        ScanResult result = getItem(position);
        ((TextView) convertView.findViewById(R.id.wifi_name)).setText(formatSSDI(result));
        ((ImageView) convertView.findViewById(R.id.wifi_img)).setimageLevel(getnormalizedLevel(result));
        return convertView;
    }

    private int getnormalizedLevel(ScanResult r) {
        int level = WifiManager.calculateSignalLevel(r.level,5);
        Log.e(getClass().getSimpleName(),"level " + level);
        return level;
    }

    private String formatSSDI(ScanResult r) {
        if (r == null || r.SSID == null || "".equalsIgnoreCase(r.SSID.trim())) {
            return "no data";
        }
        return r.SSID.replace("\"","");
    }

我稍微改变了你的showWifiListDialog：

private void showWifiListDialog(List<ScanResult> results) {
    Collections.sort(results,new Comparator<ScanResult>() {
        @Override
        public int compare(ScanResult lhs,ScanResult rhs) {
            return rhs.level > lhs.level ? 1 : rhs.level < lhs.level ? -1 : 0;
        }
    });
    AlertDialog.Builder builderSingle = new AlertDialog.Builder(
            this);
    final WifiAdapter arrayAdapter = new WifiAdapter(
            this,android.R.layout.select_dialog_item,results);

    builderSingle.setNegativeButton(getString(android.R.string.cancel),int which) {
                    String strName = arrayAdapter.getItem(which).SSID;
                    Toast.makeText(getApplicationContext(),"Selected " + strName,Toast.LENGTH_SHORT).show();
                }
            });
    AlertDialog dialog = builderSingle.create();
    dialog.show();
}

Wifi项目是

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

    <TextView
        android:textSize="16sp"
        android:padding="5dp"
        android:layout_gravity="center_vertical"
        android:id="@+id/wifi_name"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

    <ImageView
        android:id="@+id/wifi_img"
        android:layout_gravity="center_vertical"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/wifi_level" />
</LinearLayout>

而drawable wifi_level是

<?xml version="1.0" encoding="utf-8"?>
<level-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:drawable="@drawable/ic_signal_wifi_0_bar_black_24dp"
        android:maxLevel="0" />
    <item
        android:drawable="@drawable/ic_signal_wifi_1_bar_black_24dp"
        android:maxLevel="1" />
    <item
        android:drawable="@drawable/ic_signal_wifi_2_bar_black_24dp"
        android:maxLevel="2" />
    <item
        android:drawable="@drawable/ic_signal_wifi_3_bar_black_24dp"
        android:maxLevel="3" />

    <item
        android:drawable="@drawable/ic_signal_wifi_4_bar_black_24dp"
        android:maxLevel="4" />
</level-list>

我从here开始拿了五个png

对于Connection,答案是肯定的,应该是可能的.至少相应的文件.您可以实例化WifiConfiguration的对象,并使用您要连接的网络的信息(SSID和密码)提供它.这不是一件简单的事情.如果你必须考虑不同种类的密钥加密,(WPA,WEP,免费wifi).一旦你填满了对象,就必须打电话

mWifiManager.disconect();
int resId = mWifiManager.addNetwork(config);
mWifiManager.enableNetwork(resId,true);

编辑：

如果要显示带或不带挂锁的wifi信号强度图标,可以使用自定义属性

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="wifi">
        <attr name="state_locked" format="boolean" />
    </declare-styleable>
</resources>

并在ImageView的子类中更新其状态：

public class WifiImageView extends ImageView {

private static final int[] STATE_LOCKED = {R.attr.state_locked};
private boolean mWifiLocked;

public WifiImageView(Context context,AttributeSet attrs) {
    super(context,attrs);
}

@Override
public int[] onCreateDrawableState(int extraSpace) {
    final int[] drawableState = super.onCreateDrawableState(extraSpace + 1);
    if (mWifiLocked) {
        mergeDrawableStates(drawableState,STATE_LOCKED);
    }
    return drawableState;
}

public void setStateLocked(boolean locked) {
    mWifiLocked = locked;
    refreshDrawableState();
}

}

现在假设你的WifeImageView的android：src是一个选择器

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:custom="http://schemas.android.com/apk/res-auto">
    <item custom:state_locked="false" android:drawable="@drawable/wifi_level" />
    <item custom:state_locked="true" android:drawable="@drawable/wifi_level_lock" />
</selector>

在您的适配器中,您可以轻松地在两个级别列表之间切换,添加以下两行代码

boolean protectedWifi = result.capabilities.contains ("WEP") || result.capabilities.contains("WPA");
 ((WifiImageView) convertView.findViewById(R.id.wifi_img)).setStateLocked(protectedWifi);

如果result.capabilities包含WEP或WPA,则setWifi被评估为true,并且setStateLocked(protectedWifi);将根据其值在两个级别列表之间切换.当然,在wifi_item.xml中,您有两个从ImageView到自定义WifiImageView的更改.
