專案中H5網頁使用的高德地圖定位，好吧，許可權授予了還是定位不了

解決：
1.根據谷歌API，開啟WebView定位相關API。

2.設定前後對比，設定後可以定位。

完整程式碼：

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.view.ViewGroup;
import android.webkit.GeolocationPermissions;
import
 
 android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.widget.LinearLayout;

public class WebViewActivity extends AppCompatActivity {

    private WebView mWebView;//webview 控制元件.用於展示HTML 5頁面
    private LinearLayout mLlRoot;
    private
 
 LinearLayout.LayoutParams mLayoutParams;


    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_webview);
        initViews();
    }

    private void initViews() {
        mWebView = new
 
 WebView(getApplicationContext());
        mLlRoot = (LinearLayout) findViewById(R.id.ll_root);
        mLayoutParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        mLlRoot.addView(mWebView, mLayoutParams);

        WebSettings settings = mWebView.getSettings();
        settings.setJavaScriptEnabled(true);

//        settings.setDatabaseEnabled(true);

//        settings.setDomStorageEnabled(true);

        mWebView.setWebChromeClient(new WebChromeClient() {
            @Override
            public void onGeolocationPermissionsShowPrompt(String origin, GeolocationPermissions.Callback callback) {
                callback.invoke(origin, true, false);
                super.onGeolocationPermissionsShowPrompt(origin, callback);
            }
        });

        mWebView.loadUrl("file:///android_asset/map.html");
    }
}
