Question

我知道这个标题没有意义。问题是我有一个扩展ActionBarActivity的主活动（它包含所有活动中共享的所有代码）;我有另一个活动扩展了主活动;最后一个活动包含一个地图片段;我添加了所有必需的代码，我在设置内容视图中收到错误。

有人可以帮忙吗？我可以添加什么来帮助您理解我的问题？

修改

这是代码。我遗漏了许多我认为无关紧要的事情。

MainLayoutActivity.java：

public class MainLayoutActivity extends ActionBarActivity {

    @Override
    public void setContentView(int id) {


        LinearLayout linearLayoutContent = (LinearLayout) findViewById(R.id.linearLayoutContent);
        LayoutInflater inflater = (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        inflater.inflate(id, linearLayoutContent); //linrstlayoutcontent is the linearlayout that will contain the content 

    }

}

Answer 1

我不确定为什么会遇到ClassNotFoundException。您的构建中似乎缺少支持库。如果您的构建路径设置正确，请仔细检查此页面http://developer.android.com/tools/support-library/setup.html#libs-with-res。还要检查您是否将支持库中的片段与本机片段混合。

除此之外，即使您修复ClassNotFoundException，您的应用也无效。在MainLayoutActivity setContentView {}}}，您缺少致电super.setContentView(R.layout.activity_main_activity.xml);

目前linearLayoutContent将始终为null，因为未设置布局。

从您的sdk经理更新您的Google Play图书馆。

private void checkForMap() {
    try {
        // Getting Google Play availability status
        int status = GooglePlayServicesUtil
                .isGooglePlayServicesAvailable(mContext);

        // Showing status
        if (status != ConnectionResult.SUCCESS) {
            int requestCode = 10;
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status,
                    this, requestCode);
            dialog.show();

        } else { // Google Play Services are available

            // Getting reference to the SupportMapFragment of
            // activity_main.xml
            SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager()
                    .findFragmentById(R.id.map);
            // map = ((MapFragment)
            // getFragmentManager().findFragmentById(R.id.map)).getMap();

            // Getting GoogleMap object from the fragment
            googleMap = fm.getMap();
        }

        googleMap.setOnInfoWindowClickListener(this);
    } catch (Exception exception) {
        DebugHelper.printException(exception);
    }
}

Answer 3

Google地图v2始终通过Fragment活动进行扩展，因为在xml布局文件中，地图部分是按片段显示的。所以你应该使用扩展片段活动谷歌地图。请查看以下链接，了解google map v2的说明： https://developers.google.com/maps/documentation/android/start

在扩展另一个扩展ActionBarActivity的Activity的Activity中映射片段膨胀错误
