更改列表視圖的顏色是有可能改變的ListView顏色或背景顏色,每10個或15 seconds.I已經使用現有的代碼,這個列表視圖。在mycode中添加必要步驟的地方。我不希望每次選擇項目時更改用戶的顏色。如果用戶簡單地打開我的應用程序,並且自動更改背景顏色10秒。
mycode的:
public class MainActivity extends Activity {
private ListView lv;
private EditText et;
private String listview_array[] = { "ONE", "TWO", "THREE", "FOUR", "FIVE",
"SIX", "SEVEN", "EIGHT", "NINE", "TEN" };
private ArrayList<String> array_sort= new ArrayList<String>();
int textlength=0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv = (ListView) findViewById(R.id.ListView01);
et = (EditText) findViewById(R.id.EditText01);
lv.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, listview_array));
et.addTextChangedListener(new TextWatcher()
{
public void afterTextChanged(Editable s)
{
// Abstract Method of TextWatcher Interface.
}
public void beforeTextChanged(CharSequence s,
int start, int count, int after)
{
// Abstract Method of TextWatcher Interface.
}
public void onTextChanged(CharSequence s,
int start, int before, int count)
{
textlength = et.getText().length();
array_sort.clear();
for (int i = 0; i < listview_array.length; i++)
{
if (textlength <= listview_array[i].length())
{
if(et.getText().toString().equalsIgnoreCase(
(String)
listview_array[i].subSequence(0,
textlength)))
{
array_sort.add(listview_array[i]);
}
}
}
lv.setAdapter(new ArrayAdapter<String>
(MainActivity.this,
android.R.layout.simple_list_item_1, array_sort));
}
});
}
它可以使用自定義適配器...... – Shiva
