Question

我在listview项目中有一些TextView和edittexts。

我想要的是显示一些项目，数量，费率和总价...

每当数量或费率发生变化时，总价格也应该改变...... 当关注edittext时，Listitem应被视为已选中。

public class MainActivity extends Activity {

private MySimpleArrayAdapterNew sampleListAdapter;
private ArrayList<HashMap<String, String>> sampleArrayList;
private ListView listView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    listView=(ListView)findViewById(R.id.listView1);
    sampleArrayList = new ArrayList<HashMap<String, String>>();
    for(int i=0;i<100;i++)
    {
    HashMap<String, String> sampleObjectMap = new HashMap<String, String>();
    sampleObjectMap.put("value1", "aaa"+i);

    sampleObjectMap.put("value2", "666");
    sampleObjectMap.put("value3", "1");
    sampleObjectMap.put("value4", "777");
    sampleObjectMap.put("value5", "444"+i);
    sampleObjectMap.put("value6", "444"+i);
    sampleArrayList.add(sampleObjectMap);
    }

    sampleListAdapter = new MySimpleArrayAdapterNew(MainActivity.this,
            R.layout.cartitem, sampleArrayList);
    listView.setAdapter(sampleListAdapter);
}

此更改可能有所帮助。

首先，更改为listview：

<ListView
    android:id="@android:id/list" 
    android:layout_height="fill_parent" 
    android:layout_width="fill_parent"
    android:descendantFocusability="beforeDescendants"
    />

然后，在Manifest.xml中添加：

<activity android:name= ".yourActivity" android:windowSoftInputMode="adjustPan"/>

listview内的Edittext失去焦点
