我正在使用this项目并以我的方式对其进行编辑。我为每个页面使用了通用布局。该布局中有一个ListView。我正在检查页面的位置，并根据该位置设置不同的视图。
我的操作栏中有一个editText。我想根据editText的onTextChanged过滤当前页面的列表视图。一切都很好，但过滤没有发生。
这是我的完整代码：
public class MainActivity extends ActionBarActivity {
public static TextView actionbarTitle;
public static EditText listViewEditText;
public static ImageButton listViewSearch;
public static Context context;
public static ListView songslist;
public static final int MAX_PAGES = 1;
private int num_pages = 5;
public ArrayList<String> title;
public ArrayList<Long> albumId;
public ArrayList albumName;
public ArrayList songs;
public ArrayList artist;
public ArrayList songsPath;
public ArrayList songsDuration;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
context = this;
populate();
ActionBar actionBar = getSupportActionBar();
LayoutInflater inflator = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(R.layout.customactionbar, null);
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setIcon(R.drawable.ic_launcher);
actionBar.setCustomView(v);
listViewSearch = (ImageButton) findViewById(R.id.listViewSearch);
listViewEditText = (EditText) findViewById(R.id.editText);
actionbarTitle = (TextView) findViewById(R.id.text_left);
listViewSearch.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
actionbarTitle.setVisibility(View.GONE);
listViewEditText.setVisibility(View.VISIBLE);
}
});
final ViewPagerParallax pager = (ViewPagerParallax) findViewById(R.id.pager);
pager.set_max_pages(MAX_PAGES);
pager.setBackgroundAsset(R.drawable.picture);
pager.setAdapter(new my_adapter());
pager.getAdapter().notifyDataSetChanged();
if (savedInstanceState != null) {
num_pages = savedInstanceState.getInt("num_pages");
pager.setCurrentItem(savedInstanceState.getInt("current_page"), false);
}
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("num_pages", num_pages);
final ViewPagerParallax pager = (ViewPagerParallax) findViewById(R.id.pager);
outState.putInt("current_page", pager.getCurrentItem());
}
private class my_adapter extends PagerAdapter {
@Override
public int getCount() {
return num_pages;
}
@Override
public boolean isViewFromObject(View view, Object o) {
return view == o;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View) object);
}
@Override
public Object instantiateItem(final ViewGroup container, final int position) {
View new_view = null;
LayoutInflater inflater = getLayoutInflater();
new_view = inflater.inflate(R.layout.page, null);
songslist = (ListView) new_view.findViewById(R.id.listView);
if (position == 0) {
songslist.setAdapter(new CustomListViewSongs(context, title, artist, songsDuration));
} else if (position == 1) {
songslist.setAdapter(new CustomListViewSongs(context, songsDuration, artist, songsDuration));
} else if (position == 2) {
songslist.setAdapter(new CustomListViewSongs(context, songsPath, artist, songsDuration));
}
listViewEditText.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
ArrayList<String> temp = new ArrayList<String>();
int length = listViewEditText.getText().length();
temp.clear();
for (int t = 0; t < title.size(); t++) {
if (length <= title.get(t).length()) {
if (listViewEditText.getText().toString().equalsIgnoreCase((String) title.get(t).substring(0, length))) {
temp.add(title.get(t));
}
}
}
songslist.setAdapter(new CustomListViewSongs(context, temp, artist, songsDuration));
}
@Override
public void afterTextChanged(Editable s) {
}
});
container.addView(new_view);
Log.e("TAG", "" + position);
return new_view;
}
}
private void populate() {
ArrayList<Long> albumId = new ArrayList<Long>();
ArrayList artist = new ArrayList();
ArrayList title = new ArrayList();
ArrayList album = new ArrayList();
ArrayList songs = new ArrayList();
ArrayList songsPath = new ArrayList();
ArrayList songsDuration = new ArrayList();
String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";
Cursor cursor;
String[] projection = {
MediaStore.Audio.Media._ID,

while (cursor.moveToNext()) {
artist.add(cursor.getString(1));

}
cursor.close();
this.title = title;
this.albumId = albumId;
this.albumName = album;
this.songs = songs;
//this.songs = title;
this.artist = artist;

this.songsDuration = songsDuration;
//Collections.sort(this.songs, String.CASE_INSENSITIVE_ORDER);
//Collections.sort(this.albumName, String.CASE_INSENSITIVE_ORDER);
}
}
答案 0 :(得分：0)
使用自动填充textView会更容易。
