我有一個gridView，我希望在gridView中有一個用戶可以按的圖像按鈕，它將在gridView中創建另一個新視圖。我不希望所有的GridView項目都具有相同的onClick方法（因爲我添加了拖放功能，將使用長時間點擊，因爲當我這樣做時，即使我使gridView「clickable = true 「，它仍然使我的所有gridView項目都不可點擊）所以我想知道我該如何做到這一點。向gridView添加一個圖像按鈕
這裏是爲GridView的xml：
<GridView
android:id="@+id/GRIDVIEW1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="30dip"
android:numColumns="auto_fit"
android:columnWidth="60dp"
android:horizontalSpacing="10dp"
android:verticalSpacing="10dp"
android:gravity="center"
android:stretchMode="columnWidth"
android:clickable="true"
>
</GridView>
，這裏是我的自定義適配器：
package com.example.awesomefilebuilderwidget;
IMPORTS
public class GridViewAdapter extends BaseAdapter {
private Context Context;
// Keep all Images in array list
public ArrayList<Integer> drawables = new ArrayList<Integer>();
CheckBox mCheckBox=null;
// Constructor
public GridViewAdapter(Context c){
Context = c;
Log.d("GridViewAdapter", "Constructor is set");
drawables.add(R.drawable.pattern1);
Log.d("GridViewAdapter", "pattern1 added");
drawables.add(R.drawable.pattern2);
Log.d("GridViewAdapter", "pattern2 added");
drawables.add(R.drawable.trashcan);
Log.d("GridViewAdapter", "trashcan added");
drawables.add(R.drawable.ic_launcher);
Log.d("GridViewAdapter", "ic_launcher added");
}
public void setCheckBox(CheckBox checkbox){
mCheckBox=checkbox;
}
@Override
// How many items are in the data set represented by this Adapter
public int getCount() {
return drawables.size();
}
@Override
// Get the data item associated with the specified position in the
// data set
public Object getItem(int position) {
return drawables.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// Try to reuse the views
ImageView view = (ImageView) convertView;
boolean checked = (mCheckBox==null)?false:(((CheckBox) mCheckBox).isChecked());
// if convert view is null then create a new instance else reuse it
if (view == null) {
view = new ImageView(Context);
Log.d("GridViewAdapter", "new imageView added");
view.setId(R.id.iconImageView_id);
}
if(checked == true){
isSdReadable();
Log.i("GridViewAdapter", "checkbox is checked");
} else {
Log.i("GridView", "Icons not for use/checkbox not checked");
}
/* view.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
ImageView folder = new ImageView(Context);
folder.setImageResource(R.drawable.ic_launcher);
}
});*/
view.setImageResource(drawables.get(position));
view.setScaleType(ImageView.ScaleType.CENTER_CROP);
view.setLayoutParams(new android.widget.GridView.LayoutParams(70, 70));
view.setTag(String.valueOf(position));
return view;
}
}
有沒有辦法，我可以把一個ImageButton的實際GridView和設立方式onClick方法與此相同：
view.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
ImageView folder = new ImageView(Context);
folder.setImageResource(R.drawable.ic_launcher);
}
});*/
？我試過四處尋找，但我沒有真正發現任何有用的東西。
此外，我已經嘗試在構造函數中添加「add_button」（按鈕，我希望用戶將圖像作爲ic_launcher創建新視圖），但如果我這樣做，我該如何做它只有第一個gridView項目是可點擊的，不會影響其他imageViews？
