public class MainActivity extends Activity { PRivate ListView listView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); listView = (ListView) findViewById(R.id.listView1); String[] adapterData = new String[] { "Afghanistan", "Albania",… … "Bosnia"}; listView.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,adapterData)); setListViewHeightBasedOnChildren(listView); } public void setListViewHeightBasedOnChildren(ListView listView) { // 获取ListView对应的Adapter ListAdapter listAdapter = listView.getAdapter(); if (listAdapter == null) { return; } int totalHeight = 0; for (int i = 0, len = listAdapter.getCount(); i < len; i++) { // listAdapter.getCount()返回数据项的数目 View listItem = listAdapter.getView(i, null, listView); // 计算子项View 的宽高 listItem.measure(0, 0); // 统计所有子项的总高度 totalHeight += listItem.getMeasuredHeight(); } ViewGroup.LayoutParams params = listView.getLayoutParams(); params.height = totalHeight+ (listView.getDividerHeight() * (listAdapter.getCount() - 1)); // listView.getDividerHeight()获取子项间分隔符占用的高度 // params.height最后得到整个ListView完整显示需要的高度 listView.setLayoutParams(params); } }
