我有一个自定义的ListView。 每一行都有一个EditText, Buttons & TextView 。为了使点击我一直ListView的项目android:descendantFocusability="blocksDescendants"为行布局。如果我不守descendantFocusability我无法实现的动作onItemClick 。如果我继续descendantFocusability的EditText这是目前在我行未获得焦点。我想EditText可获得焦点，也是我应该可以点击每行导航到另一个Activity 。任何人都可以请帮我在这。感谢所有。

编辑：在CustomAdapter的EditText上，我试图保持onTouchListener也onClickListener ，我requestFocus的，但似乎并没有工作。

Answer 1:

请不要使用setOnItemClickListener的项目点击..我认为你应该适配器方法中使用项目视图点击

convertView.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                Toast.makeText(context, "click item",Toast.LENGTH_LONG).show();
            }
        });

从主列表项的布局中删除此

android:descendantFocusability="blocksDescendants"

感谢和享受这个代码！

Answer 2:

尝试这一行添加到您的活动在manifest.xml

android:windowSoftInputMode="stateHidden|adjustResize|adjustPan"

Answer 3:

you do like this:

first set in your listview android:focusable="false";

那么你要被点击行：这个在您的customAdapterü应该做这样的

 v.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) { 
                // TODO Auto-generated method stub
            Toast.makeText(context, "Hello world",2000).show(); 

            }
        });

它将工作。默认情况下，您的项目现在应该点击选项，当你让机器人：在列表视图可聚焦=“假”。无需在列表视图中使用-descendantFocusability。

public class AndroidCustomListViewActivity extends Activity {
    private ListView myList;
    private MyAdapter myAdapter;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        myList = (ListView) findViewById(R.id.MyList);
        myList.setItemsCanFocus(true);
        myAdapter = new MyAdapter();
        myList.setAdapter(myAdapter);

    }

    public class MyAdapter extends BaseAdapter {

        public MyAdapter() {
            mInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            for (int i = 0; i < 20; i++) {
                ListItem listItem = new ListItem();
                listItem.caption = "Caption" + i;
                myItems.add(listItem);

    class ViewHolder {
        EditText caption;
    }

    class ListItem {
        String caption;

Answer 5:

main.xml中

<ListView
android:id="@+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:animationCache="false"
android:scrollingCache="false"
android:smoothScrollbar="true" >
</ListView>

创建ArrayList中添加数据到ArrayList中。

lv=(ListView)findViewById(R.id.listView1);
lv.setItemsCanFocus(true);

for(int i=0;i<30 data-blogger-escaped-br="" data-blogger-escaped-i=""> list.add(i);
}

1）创建为ListView适配器，并设置位置标记为的EditText。

2）一般情况下，滚动条位置时将change.So，你必须得到的EditText标签，并将其设置到EditText上id.from你能够避免物品位置的变化。

holder.caption = (EditText) convertView
.findViewById(R.id.editText12);
holder.caption.setTag(position); 
holder.caption.setText(list.get(position).toString());
convertView.setTag(holder);

}else {
holder = (ViewHolder) convertView.getTag();
}
int tag_position=(Integer) holder.caption.getTag();
holder.caption.setId(tag_position);

最后，文观察者添加到的EditText和存储变为列表中的正确位置。

holder.caption.addTextChangedListener(new TextWatcher() {

             @Override
            public void onTextChanged(CharSequence s, int start, int before,
                    int count) {
                      final int position2 = holder.caption.getId();
                      final EditText Caption = (EditText) holder.caption;
                      if(Caption.getText().toString().length()>0){
                       list.set(position2,Integer.parseInt(Caption.getText().toString()));
                      }else{
                       Toast.makeText(getApplicationContext(), "Please enter some value", Toast.LENGTH_SHORT).show();
                      }

                  }

             @Override
            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {
                // TODO Auto-generated method stub
            }

             @Override
            public void afterTextChanged(Editable s) {

            }

         });
