android - ListView 到 Gridview 导致 RuntimeException : Your content must have a ListView whose id attribute is 'android.R.id.list'

Question

我有一个应用程序，它在运行时在 ListView 中显示图像列表(参见屏幕截图)。现在我想更改 GridView(而不是 ListView)，我收到上述错误并且我不确定如何解决这个问题。我认为它不像 setListAdapter 方法，因为它只适用于 ListView 但不适用于 GridView。

截图如下:

我正在使用改造从网络上抓取图像。

//这是它不喜欢的代码:

public void success(MoviesResponse moviesresponse, Response response) {
   movieList = moviesresponse.getResults();

   adapter adapt = new adapter(getApplicationContext(),R.layout.item_file,movieList);

   setListAdapter(adapt);

}

这是我的 activity_main:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
   android:layout_height="match_parent" tools:context=".MainActivity">

   <GridView
       xmlns:android="http://schemas.android.com/apk/res/android"
       xmlns:tools="http://schemas.android.com/tools"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:columnWidth="150dp"
       android:numColumns="auto_fit"
       android:verticalSpacing="0dp"
       android:horizontalSpacing="0dp"
       android:stretchMode="columnWidth"
       tools:context=".MainActivityFragment"
       android:id="@+id/gridview_movie">
   </GridView>

</RelativeLayout>

这是堆栈跟踪:

更新:这是请求的 MainActivity 和适配器

这是完整的 MainActivty:

public class MainActivity extends ListActivity {




    List<Movie> movieList;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        RestAdapter restAdapter = new RestAdapter.Builder()
                .setEndpoint("http://api.themoviedb.org/3")
                .setRequestInterceptor(new RequestInterceptor() {
                    @Override
                    public void intercept(RequestFacade request) {
                        request.addEncodedQueryParam("sort_by", "popularity.des");
                        request.addEncodedQueryParam("api_key","YOURAPIKEY");
                    }
                })
                .setLogLevel(RestAdapter.LogLevel.FULL)
                .build();

        MovieAPI service = restAdapter.create(MovieAPI.class);

        service.getPopularMovies(new Callback<MoviesResponse>() {
            @Override
            public void success(MoviesResponse moviesresponse, Response response) {
                movieList = moviesresponse.getResults();

                movieList = moviesresponse.getResults();

                adapter adapt = new adapter(getApplicationContext(),R.layout.item_file,movieList);

                setListAdapter(adapt);
            }

            @Override
            public void failure(RetrofitError error) {
                Toast.makeText(MainActivity.this, error.getMessage(), Toast.LENGTH_LONG).show();
            }
        });


    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);

        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

Answer 1

问题是您正在使用 ListActivity，即。您的 Activity 扩展了 ListActivity，因此使用 GridView 将不起作用。

相反，您应该使用普通的 Activity，然后使用布局中的 GridView。

在你的 onCreate 中这样的东西应该可以解决问题:

setContentView(R.layout.main);
GridView mGridView = (GridView) findViewById(R.id.gridview_movie);

adapter adapt = new adapter(getApplicationContext(),R.layout.item_file, movieList);
mGridView.setAdapter(adapt);
