我尝试在我有Main活动的地方创建app,在点击Options Item - Map后创建MapActivity。我无法解决这个问题。

如果您在AndroidManifest中声明了此活动,我会看到此错误,但我无法做到。

public boolean onOptionsItemSelected(MenuItem item) {
        switch(item.getItemId()){
        case R.id.Mapy:

            Intent intent = new Intent(this,Map.class);
            startActivity(intent);


            break;
        default:
            return super.onOptionsItemSelected(item);
        }
        return true;
    }

        mapView.setStreetView(true);


    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }

}

答案 0 :(得分:1)

好像你忘了宣布活动:

pl.pawelfrydrych.flyingball.Map

在你的AndroidManifest.xml


在另一个activity标记下面的Manifest.xml中添加类似的内容:

    <activity
        android:name="pl.pawelfrydrych.flyingball.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <!-- add this here: -->
    <activity
        android:name="pl.pawelfrydrych.flyingball.Map"
        android:label="@string/map_title" >
    </activity>
