ListView的Item中含有EditText,获取EditText里面的值并且刷新ListView值不改变_JAVA_编程开发_程序员俱乐部

最近项目中用ListView ,ListView的item是EditText,然后设置EditText的值，一拉ListVIew,EditText中的值就改变了，然后自己就上网找了资料，现在将方法总结一下，菜鸟第一次写博客，大牛勿喷

?

main.xml 里面只有一个ListView

class="html" name="code"><?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"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/listView"
        android:cacheColorHint="#000000"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" >
    </ListView>

</LinearLayout>

listView 每一个item布局，里面只有一个EditText

<?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"
    android:orientation="vertical" >

    <EditText
        android:id="@+id/editText1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">

    </EditText>

</LinearLayout>

			convertView = LayoutInflater.from(getApplication()).inflate(R.layout.listview_item, null);
			
			final EditText editText = (EditText)convertView.findViewById(R.id.editText1);
			editText.setText(str);
			
			//为editText设置TextChangedListener，每次改变的值设置到hashMap
			//我们要拿到里面的值根据position拿值
			editText.addTextChangedListener(new TextWatcher() {
				@Override
				public void onTextChanged(CharSequence s, int start, int before, int count) {
					
				}
				
				@Override
				public void beforeTextChanged(CharSequence s, int start,

				}
				
				@Override
				public void afterTextChanged(Editable s) {
					//将editText中改变的值设置的HashMap中
					hashMap.put(position, s.toString());
				}

			//如果hashMap不为空，就设置的editText
			if(hashMap.get(position) != null){
				editText.setText(hashMap.get(position));
			}
			
			
			return convertView;

如果你想得到每个editText中的值，根据position就可以拿到啦
