android6.0下webview的定位權限設置

WebView webView = (WebView)findViewById(R.id.webview);
WebSettings webSettings = webView.getSettings();

//webview支持js腳本
webSettings.setJavaScriptEnabled(true);

//啓用數據庫  
webSettings.setDatabaseEnabled(true);    

//設置定位的數據庫路徑  
String dir = this.getApplicationContext().getDir("database", Context.MODE_PRIVATE).getPath(); 
webSettings.setGeolocationDatabasePath(dir);   

//啓用地理定位
webSettings.setGeolocationEnabled(true);  

//開啓DomStorage緩存
webSettings.setDomStorageEnabled（true）  

//配置權限
webView.setWebChromeClient(new WebChromeClient() {
  @Override
  public void onReceivedIcon(WebView view, Bitmap icon) {
     super.onReceivedIcon(view, icon);

}

@Override
public void onGeolocationPermissionsShowPrompt(String origin,Callback callback) {
  callback.invoke(origin, true, false);  
  super.onGeolocationPermissionsShowPrompt(origin, callback);

}
});

//在Androidmanifest.xml中開啓權限
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />  
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

Android6.0版本需要加上：

            if (Build.VERSION.SDK_INT >= 23) {
                int checkPermission = ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.ACCESS_COARSE_LOCATION);
                if (checkPermission != PackageManager.PERMISSION_GRANTED) {
                    ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
                    ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
                    Log.d("TTTT", "彈出提示");
                }
            }
