Question

我在我的应用中使用谷歌地图。我无法获得地图图块。我只看到一个黑屏。我现在已经挣扎了3天。我在我的计算机上生成了地图api密钥，并在myifest.xml文件中添加了所有权限。但仍然无法获得地图图块。 ActivityMap.java `

package com.example.locatometer;

import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.Handler;

import com.example.locatometer.utils.Tracker;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;

public class ActivityMap extends MapActivity{
    MapView mapView;
    MapController controller;
    Tracker tracker;
    Handler locationHandler = new Handler();
    GeoPoint mapPoint;

    @Override
    protected void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.activity_current_location_on_map);
        init();
    }
    private void init() {
        mapView = (MapView) findViewById(R.id.map);
        mapView.setBuiltInZoomControls(true);
        mapView.setSatellite(true);
        controller = mapView.getController();

    }
    @Override
    protected void onResume() {
        super.onResume();

    }
    @Override
    protected void onPause() {
        super.onPause();

    }
    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }

}

    </application>

</manifest>

Answer 1

它可能没有关系，但是当我面对类似的问题时，我做过一次。在manifest put

中的应用程序标记下

  android:hardwareAccelerated="false"

可能不行，但值得一试。
