在ListView控件setOnItemClickListener不开火 [英] setOnItemClickListener on ListView doesn't firing
问题描述
我得到我的SD卡的文件列表，并在ListView像这样的自定义适配器的帮助下显示出来：
I get the list of files of my SD card and display it in the listView like with the help of custom adapter like that:
adapter = new ArrayAdapter<Item>(this,
R.layout.file_manager, R.id.checkedTextItem,
fileList)
{
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// creates view
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.check_item, null);
CheckedTextView textView = (CheckedTextView) view
.findViewById(R.id.checkedTextItem);
// put the image on the text view
textView.setCompoundDrawablesWithIntrinsicBounds(
fileList[position].icon, 0, 0, 0);
textView.setTextColor(Color.WHITE);
textView.setText(fileList[position].file);
if(fileList[position].icon == R.drawable.directory_icon)
textView.setCheckMarkDrawable(null);
// add margin between image and text (support various screen
// densities)
int dp5 = (int) (5 * getResources().getDisplayMetrics().density + 0.5f);
textView.setCompoundDrawablePadding(dp5);
return view;
}
};
我想实施setonitemclicklistener或类似的东西听的检测项目单击事件。我的onCreate（）在活动方式：
I want to implement setonitemclicklistener or something like that to listen to the detect items click events. My onCreate() method in Activity:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.file_manager);
lv = (ListView)findViewById(R.id.fileManagerList);
loadFileList();
file_list = findViewById(R.id.filesList);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) {
//String selectedFromList = (lv.getItemAtPosition(myItemInt).toString());
Toast toast = Toast.makeText(getApplicationContext(), "Hello world!", Toast.LENGTH_LONG);
toast.show();
}
});
}
我的活动的XML：
My xml of Activity:
<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fileManager"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<ListView
android:background="#000000"
android:focusable="false"
android:id="@+id/fileManagerList"
android:layout_width="fill_parent"
android:layout_above="@+id/closecalmlayout"
android:layout_height="wrap_content" >
</ListView>
<LinearLayout
android:id="@+id/closecalmlayout"
android:layout_alignParentBottom="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="1.0" >
<Button
android:id="@+id/btnOk"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="5dip"
android:layout_marginTop="5dip"
android:layout_weight=".50"
android:text="Attach files"
/>
<Button
android:id="@+id/btnCancel"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="5dip"
android:layout_marginRight="5dip"
android:layout_marginTop="5dip"
android:layout_weight=".50"
android:text="Do not attach"
/>
</LinearLayout>
</RelativeLayout>
和我CheckedTextView活动
And my CheckedTextView Activity
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp">
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/checkedTextItem"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:checkMark="?android:attr/listChoiceIndicatorMultiple"
android:textColor="#000000"
android:focusable="false"
android:paddingLeft="10dip"
android:paddingRight="6dip"
android:typeface="sans" android:textSize="16dip"/>
</LinearLayout>
但是，当我点击的项目，没有任何反应。我试图让setOnItemClickListener在onResume（）方法，但有相同的效果。我也试过onclicklistener - 同样的效果。这有什么原因吗？
But when I click on items, nothing happens. I tried to make setOnItemClickListener in the onResume() method, but had the same effect. I also tried onclicklistener - the same effect. What's the reason of it?
推荐答案
在我看来，有些观点正在从你的列表视图的焦点，当你知道它查看它，使用的android：可聚焦=FALSE在XML中的这一观点，它应该做的伎俩。
It seems to me that some view is taking the focus from your list view, when you know which view it is, use android:focusable="false" on that view in your xml, and it should do the trick.
我想你的code和onItemClicked被调用，这是我getView（）：
I tried your code and onItemClicked is being called, this is my getView():
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if(view == null){
LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = vi.inflate(R.layout.row, null);
}
CheckedTextView textView = (CheckedTextView) view.findViewById(R.id.checked);
textView.setText("Hello"); //test, you can do whatever you want with this
int dp5 = (int) (5 * getResources().getDisplayMetrics().density + 0.5f);
textView.setCompoundDrawablePadding(dp5);
return view;
}
我如何设置适配器（MyAdapter）：
How I set the adapter (MyAdapter):
MyAdapter adapter = new MyAdapter(this, 0, arrayList);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
Toast.makeText(PlayingAroundActivity.this, "Hello", Toast.LENGTH_LONG).show();
}
});
