android ListView写一个电影列表

以下是一个简单的电影列表示例，其中包含电影名称、导演和演员列表： 1. 创建一个新的Android项目，然后在布局文件中添加一个ListView组件： ``` <ListView android:id="@+id/movie_list" android:layout_width="match_parent" android:layout_height="match_parent"/> ``` 2. 在Activity中获取ListView组件的引用，并创建一个Movie类作为数据模型： ``` public class Movie { private String title; private String director; private List<String> actors; public Movie(String title, String director, List<String> actors) { this.title = title; this.director = director; this.actors = actors; } public String getTitle() { return title; } public String getDirector() { return director; } public List<String> getActors() { return actors; } } public class MainActivity extends AppCompatActivity { private ListView movieList; private List<Movie> movies; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); movieList = findViewById(R.id.movie_list); movies = new ArrayList<>(); movies.add(new Movie("The Shawshank Redemption", "Frank Darabont", Arrays.asList("Tim Robbins", "Morgan Freeman"))); movies.add(new Movie("The Godfather", "Francis Ford Coppola", Arrays.asList("Marlon Brando", "Al Pacino", "James Caan"))); movies.add(new Movie("The Dark Knight", "Christopher Nolan", Arrays.asList("Christian Bale", "Heath Ledger", "Aaron Eckhart"))); MovieAdapter adapter = new MovieAdapter(this, movies); movieList.setAdapter(adapter); } } ``` 3. 创建一个自定义适配器MovieAdapter，用于将Movie对象显示在ListView中： ``` public class MovieAdapter extends ArrayAdapter<Movie> { private Context context; private List<Movie> movies; public MovieAdapter(Context context, List<Movie> movies) { super(context, R.layout.movie_item, movies); this.context = context; this.movies = movies; } @Override public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) { LayoutInflater inflater = LayoutInflater.from(context); convertView = inflater.inflate(R.layout.movie_item, parent, false); } TextView titleView = convertView.findViewById(R.id.title); TextView directorView = convertView.findViewById(R.id.director); TextView actorsView = convertView.findViewById(R.id.actors); Movie movie = movies.get(position); titleView.setText(movie.getTitle()); directorView.setText("Director: " + movie.getDirector()); actorsView.setText("Actors: " + TextUtils.join(", ", movie.getActors())); return convertView; } } ``` 4. 创建一个布局文件movie_item.xml，用于定义ListView中每个电影项的布局： ``` <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:padding="16dp"> <TextView android:id="@+id/title" android:layout_width="match_parent" android:layout_height="wrap_content" android:textSize="18sp" android:textStyle="bold"/> <TextView android:id="@+id/director" android:layout_width="match_parent" android:layout_height="wrap_content"/> <TextView android:id="@+id/actors" android:layout_width="match_parent" android:layout_height="wrap_content"/> </LinearLayout> ``` 5. 运行应用程序，您应该会看到一个电影列表，其中包含上面定义的电影。 这只是一个简单的示例，您可以根据需要更改布局和数据模型来创建更复杂的电影列表。
