Android: only some rows are displayed at first run

Question

The Listview is displaying some rows instead of all items (sometimes, it's displaying nothing), I couldn't understand why this is happenning. It occurs at first run. After that, it works well, with all items from database filled on the screen. I put vertical orientation in my linear layout xml files and wrap_content height. But the problem is not solved.

This is my main activity :

public class MainActivity extends Activity {

public static final String PREFS_NAME = "MyPrefsFile1";

private TextView mTextView;
private ListView mListView;


ArrayList<WordDefinition> allWordDefinitions=new ArrayList<WordDefinition>();

DictionaryDatabase DictionaryDatabase;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);    
    setContentView(R.layout.main);
    mTextView = (TextView) findViewById(R.id.text);
    mListView = (ListView) findViewById(R.id.list);
    DictionaryDatabase=new DictionaryDatabase(this); 
    allWordDefinitions=DictionaryDatabase.getAllWords(); 

    Collections.sort(allWordDefinitions, new CustomComparator());    
        mListView.setAdapter(new BaseAdapter() {

        @Override
        public View getView(int position, View view, ViewGroup arg2) {
            if (view==null) {
                view=getLayoutInflater().inflate(R.layout.list_item, arg2, false);
            }
            TextView textView=(TextView) view.findViewById(R.id.listItemTextView);
            textView.setText(allWordDefinitions.get(position).word);

            return view;
        }

        @Override
        public long getItemId(int arg0) {
            // TODO Auto-generated method stub
            return 0;
        }

        @Override
        public Object getItem(int arg0) {
            // TODO Auto-generated method stub
            return null;
        }

        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return allWordDefinitions.size();
        }
    });

    mListView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View view, int position,
                long arg3) {
            Intent intent =new Intent(MainActivity.this, WordDefinitionDetailActivity.class);
            intent.putExtra("word", allWordDefinitions.get(position).word);
            intent.putExtra("definition", allWordDefinitions.get(position).definition);


            startActivity(intent);
        }
    });


    handleIntent(getIntent());
}

@Override
protected void onNewIntent(Intent intent) {
    handleIntent(intent);
}

private void handleIntent(Intent intent) {
    if (Intent.ACTION_VIEW.equals(intent.getAction())) {
        Intent wordIntent = new Intent(this, WordActivity.class);
        this.finish();
        wordIntent.setData(intent.getData());
        startActivity(wordIntent);
    } else if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        String query = intent.getStringExtra(SearchManager.QUERY);
        showResults(query);

    }
}

private void showResults(String query) {

    Cursor cursor = managedQuery(DictionaryProvider.CONTENT_URI, null, null,
                            new String[] {query}, null);

    if (cursor == null) {
        mTextView.setText(getString(R.string.no_results, new Object[] {query}));
    } else {
        int count = cursor.getCount();
        String countString = getResources().getQuantityString(R.plurals.search_results,
                                count, new Object[] {count, query});
        mTextView.setText(countString);

        String[] from = new String[] { DictionaryDatabase.KEY_WORD,
                                       DictionaryDatabase.KEY_DEFINITION };

        int[] to = new int[] { R.id.word,
                               R.id.definition };

        SimpleCursorAdapter words = new SimpleCursorAdapter(this,
                                      R.layout.result, cursor, from, to);
        mListView.setAdapter(words);

        mListView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Intent wordIntent = new Intent(getApplicationContext(), WordActivity.class);
                Uri data = Uri.withAppendedPath(DictionaryProvider.CONTENT_URI,
                                                String.valueOf(id));
                wordIntent.setData(data);
                startActivity(wordIntent);

            }
        });
    }
}


public class CustomComparator implements Comparator<WordDefinition> {          

   @Override
       public int compare(WordDefinition p1, WordDefinition p2) {
          return p1.word.compareTo(p2.word);
       }
    }

}

WorDefinition (Array List):

public class WordDefinition {
String word,definition;

public WordDefinition(String word,ArrayList<String> alldefinition) {
    this.word=word;

    StringBuilder stringBuilder=new StringBuilder();
    for (String string : alldefinition) {
        stringBuilder.append(string);
    }       
    this.word=stringBuilder.toString();

}

public WordDefinition(String word,String alldefinition) {
    this.word=word;     
    this.definition=alldefinition;

   } 


 }

DictionaryDatabase (snippet)

public ArrayList<WordDefinition> getAllWords() {
ArrayList<WordDefinition> arrayList=new ArrayList<WordDefinition>();
SQLiteDatabase database=mDatabaseOpenHelper.getReadableDatabase();

String selectAllQueryString="SELECT * FROM "+FTS_VIRTUAL_TABLE;
Cursor cursor=database.rawQuery(selectAllQueryString, null);

if (cursor.moveToFirst()) {
    do {            
        WordDefinition wordDefinition=new WordDefinition(cursor.getString(cursor.getColumnIndex(KEY_WORD)), cursor.getString(cursor.getColumnIndex(KEY_DEFINITION)));
        arrayList.add(wordDefinition);              
    } while (cursor.moveToNext());          
}   
return arrayList;
}

Answer 1

Sometimes height ListView calculate incorrect.

Android: wrap_content is not working with ListView

You can use one adapter and one ListView instead of Two ListViews. Use types for items in this adapter. In this way you can remove wrap_content and set match_parent for height attribute in ListView
