Android ListView 只顯示一行文字

效果圖如下：

1. package com.lxy;
3. import java.util.ArrayList;
4. import java.util.List;
6. import android.app.Activity;
7. import android.os.Bundle;
8. import android.util.Log;
9. import android.view.View;
10. import android.widget.AdapterView;
11. import android.widget.AdapterView.OnItemClickListener;
12. import android.widget.ArrayAdapter;
13. import android.widget.ListView;
15. public class AppMain extends Activity {
17. private ListView listView;
18. List<String> data;
19. ArrayAdapter<String> adapter;
21. public void onCreate(Bundle savedInstanceState) {
22. super.onCreate(savedInstanceState);
23. setContentView(R.layout.main);
25. listView = (ListView)findViewById(R.id.listview01);
27. //ArrayAdapter較為簡單，只能顯示一行文字。
28. data = new ArrayList<String>();
29. for(int i = 0; i < 10; i++){
30. data.add("Item_"+i);
31. }
32. adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, data);
33. listView.setAdapter(adapter);
35. //這裡是監聽事件:點擊哪一條就刪除那一條
36. listView.setOnItemClickListener(new OnItemClickListener() {
37. public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
38. long arg3) {
39. Log.d("test", "arg2 = "+arg2+", arg3 = "+arg3);
40. data.remove(arg2);
41. listView.setAdapter(adapter);
42. }
43. });
44. }
46. }
