ListView中的Android EditText无法编辑

Question

我无法编辑EditText。如何实现？ ，也想知道如何从所有的Edittext中获取数据。我给我的班，在这里

xml文件MainActivity.java

package com.example.listviewdynamic; 

import java.util.ArrayList; 
import java.util.List; 

import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.view.ViewGroup; 
import android.widget.AdapterView; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.ListView; 

public class MainActivity extends Activity { 

Button submit; 
public static final String[] commodity = new String[] { "1", "2", 
     "3", "4" }; 
public static final String[] quantity = new String[] { "50", "40", "30", 
     "15", }; 
public static final String[] rate = new String[] { "2", "5", "3", "121", }; 
public static final String[] issue_qty = new String[] { "0.0", "0.0", 
     "0.0", "0.0", }; 

ListView listView; 
List<RowItem> rowItems; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    rowItems = new ArrayList<RowItem>(); 
    for (int i = 0; i < commodity.length; i++) { 
     RowItem item = new RowItem(commodity[i], quantity[i], rate[i], 
       issue_qty[i]); 
     rowItems.add(item); 
    } 
    submit = (Button) findViewById(R.id.submit); 
    listView = (ListView) findViewById(R.id.list); 
    listView.setItemsCanFocus(true); 
    listView.setClickable(false); 
    CustomListAdapter adapter = new CustomListAdapter(this, rowItems); 
    listView.setAdapter(adapter); 

    // How to get the data ? 
    submit.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // Code To get data with id's from EditText 
     } 
    }); 

} 

public void onItemSelected(AdapterView<?> listView, View view, 
     int position, long id) { 
    EditText yourEditText = (EditText) view.findViewById(R.id.issue_qty); 
    listView.setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS); 
    yourEditText.requestFocus(); 
} 

public void onNothingSelected(AdapterView<?> listView) { 
    listView.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS); 
} 

} 

CustomListAdapter.java

package com.example.listviewdynamic; 

import java.util.List; 

import android.app.Activity; 
import android.content.Context; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.EditText; 
import android.widget.TextView; 

public class CustomListAdapter extends BaseAdapter { 
Context context; 
List<RowItem> rowItems; 

public CustomListAdapter(Context context, List<RowItem> items) { 
    this.context = context; 
    this.rowItems = items; 
} 

private class ViewHolder { 

    TextView item; 
    TextView quantity; 
    TextView rate; 
    EditText issue_quantity; 
} 

public View getView(int position, View convertView, ViewGroup parent) { 
    ViewHolder holder = null; 

    LayoutInflater mInflater = (LayoutInflater) context 
      .getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 
    if (convertView == null) { 
     convertView = mInflater.inflate(R.layout.list_items, null); 
     holder = new ViewHolder(); 
     holder.quantity = (TextView) convertView 
       .findViewById(R.id.quantity); 
     holder.item = (TextView) convertView.findViewById(R.id.item); 
     holder.rate = (TextView) convertView.findViewById(R.id.rate); 
     holder.issue_quantity = (EditText) convertView 
       .findViewById(R.id.issue_qty); 
     convertView.setTag(holder); 
    } else { 
     holder = (ViewHolder) convertView.getTag(); 
    } 

    RowItem rowItem = (RowItem) getItem(position); 

    holder.quantity.setText(rowItem.getQuantity()); 
    holder.item.setText(rowItem.getItem()); 
    holder.rate.setText(rowItem.getRate()); 
// holder.issue_quantity.setText(rowItem.getIssue_quantity()); 

    return convertView; 
} 

@Override 
public int getCount() { 
    return rowItems.size(); 
} 

@Override 
public Object getItem(int position) { 
    return rowItems.get(position); 
} 

@Override 
public long getItemId(int position) { 
    return rowItems.indexOf(getItem(position)); 
} 
} 

RowItem.java

package com.example.listviewdynamic; 

public class RowItem { 

private String rate; 
private String quantity; 
private String item; 
private String issue_quantity; 

public RowItem(String item, String quantity, String rate, String issueQTY) { 
    this.issue_quantity = issueQTY; 
    this.item = item; 
    this.quantity = quantity; 
    this.rate = rate; 
} 

public String getRate() { 
    return rate; 
} 

public void setRate(String rate) { 
    this.rate = rate; 
} 

public String getQuantity() { 
    return quantity; 
} 

public void setQuantity(String quantity) { 
    this.quantity = quantity; 
} 

public String getItem() { 
    return item; 
} 

public void setItem(String item) { 
    this.item = item; 
} 

public String getIssue_quantity() { 
    return issue_quantity; 
} 

public void setIssue_quantity(String issue_quantity) { 
    this.issue_quantity = issue_quantity; 
} 

} 

activity_main.xml中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:orientation="vertical" > 

<ListView 
    android:id="@+id/list" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" /> 

<Button 
    android:id="@+id/submit" 
    android:layout_width="wrap_content" 
    android:layout_gravity="center_horizontal" 
    android:layout_height="wrap_content" 
    android:text="Submit" > 
</Button> 

</LinearLayout> 

个

list_items.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" > 

<TextView

EditText s的不是设计内部ListView s至使用。或者，您可以使用ScrollView并动态填充EditText。
