android.widget.EditText не может быть приведен к android.view.ViewGroup

Question

Я не знаю, в чем проблема с этим расположение:

<EditText 
    android:id="@+id/search" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:drawableRight="@android:drawable/ic_search_category_default" 
    android:hint="Search..."> 


<ListView 
    android:id="@+id/lv_data" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"  
    android:layout_below="@id/search"> 
</ListView> 

<TextView 
    android:id="@+id/empty" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_below="@id/lv_data" 
    android:layout_marginLeft="20dp" 
    android:text="Not found!"> 
</TextView></EditText></RelativeLayout> 

вот код:

импорт java.util.List;

import android.os.Bundle; 
import android.app.Activity; 
import android.content.Intent; 
import android.text.Editable; 
import android.text.TextWatcher; 
import android.view.View;

import android.widget.AdapterView.OnItemClickListener; 
import android.widget.ArrayAdapter; 
import android.widget.EditText; 
import android.widget.ListView; 

public class MainActivity extends Activity implements TextWatcher, OnItemClickListener 
{ 
    private EditText search; 
    private ListView lv; 
    private DatabaseHelper dbHelper; 
    private ArrayAdapter<Kamus> adapter; 
    private List<Kamus> ListKamus; 

    protected void oncreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     lv = (ListView) findViewById(R.id.lv_data); 
     lv.setEmptyView(findViewById(R.id.empty)); 
     search = (EditText) findViewById(R.id.search); 

     dbHelper = DatabaseHelper.getInstance(this); 

     setData(); 

     search.addTextChangedListener(this); 
     lv.setOnItemClickListener(this); 
    } 

    private void setData() 
    { 
     ListKamus = dbHelper.getAllKamus(); 

     adapter = new ArrayAdapter<Kamus>(this, android.R.layout.simple_expandable_list_item_1, ListKamus); 
     lv.setAdapter(adapter); 
    } 

    @Override 
    public void afterTextChanged(Editable arg0) 
    { 
    } 

    @Override 
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) 
    { 
    } 

    @Override 
    public void onTextChanged(CharSequence s, int arg1, int arg2, int arg3) 
    { 
     adapter.getFilter().filter(s.toString()); 
    } 

    @Override 
    public void onItemClick(AdapterView<?> arg0, View arg1, int position, long id) 
    { 
     Bundle b = new Bundle(); 
     b.putString("istilah", adapter.getItem(position).getIstilah()); 
     b.putString("arti", adapter.getItem(position).getArti()); 

     Intent i = new Intent(this, ArtiActivity.class); 
     i.putExtras(b); 
     startActivity(i); 
    } 
    }

Answer 1

ваш EditText тег не закрыт на месте. у вас есть закрыл его после TextBox. Элемент EditText не содержит других элементов ui.

так что если предположить, что остальные элементы, такие как ListView дети EditText, и поэтому он говорит EditText наклоняет быть отлит в ViewGroup

Answer 2

Это потому, что у вас есть закрыть ваши </EditText> после другой виджет (UI).

Так просто удалить этот замкнутый тег после ListView и TextView и сделать так:

<EditText 
android:id="@+id/search" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:drawableRight="@android:drawable/ic_search_category_default" 
android:hint="Search..."/> // Close your Tag here 

Answer 3

EditText следует закрыть, как это

<EditText 
android:id="@+id/search" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:drawableRight="@android:drawable/ic_search_category_default" 
android:hint="Search..."/>
