如何使用searchview搜索數據？

Question

public Cursor searchByInputText(String inputText) throws SQLException { 

    String query = "SELECT tag as _id," + 
      TABLE_CONTACTS + " from " + TABLE_CONTACTS + 
      " where " + TABLE_CONTACTS + " MATCH '" + inputText + "';"; 
    SQLiteDatabase db = this.getReadableDatabase(); 
    Cursor Cursor = db.rawQuery(query,null); 

    if (Cursor != null) { 
     Cursor.moveToFirst(); 
    } 
    return Cursor; 

} 

我試過上面的代碼，但我無法搜索。

我試圖獲取標記字段數據，無論存儲在我的數據庫中，一旦我在搜索框中搜索它不顯示我的數據庫中的任何數據。

嘗試使用搜索查看的setOnQueryTextListener

類似的東西：

new SearchView.OnQueryTextListener() { 
    @Override 
    public boolean onQueryTextChange(String newText) { 
     // this is called when text changes in SearchView 
     textView.setText(newText); 
    } 

    @Override 
    public boolean onQueryTextSubmit(String query) { 
     // this is called when Search Button is clicked 
     textView.setText(query); 
    } 
}
