    <ListView
        android:id="@+id/list_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</LinearLayout>

public class MainActivity extends AppCompatActivity {
    private String[] data={"apple","banana","Orange","Pear","watermelon","Mango",
    "Good","cat","dog","Grape","cxbg","cdstgdr","d","srw","swws","qweter","dfaw","aew3rwa","wee","wrwqww"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ArrayAdapter<String> adapter=new ArrayAdapter<String>(
                MainActivity.this,android.R.layout.simple_list_item_1,data);
        ListView listView=(ListView) findViewById(R.id.list_view);
        listView.setAdapter(adapter);
    }
}

数组中元素无法直接传递给ListView,需要借助适配器来完成。

最后需要调用ListView的setAdapter()方法，将构造好的适配器对象传递进去。
