我們看一下最終所需要的效果圖：
說明：
思路如下：
預設将我們的組合控件設定為orientation 是vertical。 首先一行五個，那麼一行以一個orientation 為horizontal 的線性布局包起來。然後在一行結束後，将orientation 的線性布局添加進組合控件裡面來，不足五個則按需添加進來。
public class tablerow {
private tablecell[] cell;
public tablerow(tablecell[] cell) {
this.cell = cell;
}
public int getsize() {
return cell.length;
public tablecell getcellvalue(int index) {
if (index >= getsize()) {
return null;
return cell[index];
public int getcellcount() {
public int getlastcellcount() {
return lastrowcount;
另外一個類用來表示gridview 每行的列個，這裡我們取名為tablecell，代碼如下：
static public class tablecell {
private object value;
public tablecell(object value) {
this.value = value;
public object getvalue() {
return value;
并且我們還需要為gridview 設定一個外部可添加資料的方法，代碼如下：
public void setadapter(appsadapter appsadapter) {
this.adapter = appsadapter;
this.setorientation(linearlayout.vertical);
bindview();
其中，appsadapter 是一個自定義的baseadapter ，代碼很簡單，這裡就不列出來了。關鍵的還是要看bindview ，這個方法是本篇gridview 顯示資料的核心方法，代碼如下：
void bindview() {
removeallviews();
int count = adapter.getcount();
tablecell[] cell = null;
int j = 0;
linearlayout layout;
tablerowslist = new arraylist<hashmap<string, object>>();
for (int i = 0; i < count; i++) {
j++;
final int position = i;
if (j > getcolumncount() || i == 0) {
cell = new tablecell[getcolumncount()];
final view view = adapter.getview(i, null, null);
view.setontouchlistener(new ontouchlistener() {
@override
public boolean ontouch(view v, motionevent event) {
// todo auto-generated method stub
uncheckpressed();
checkrowid = -1;
checkcolumnid = -1;
if (onitemclickevent != null) {
onitemclickevent.onitemclick(position, event, view);
return false;
});
view.setonlongclicklistener(new onlongclicklistener() {
public boolean onlongclick(view v) {
if (onlongpress != null) {
onlongpress.onlongpress(v);
return true;
cell[j - 1] = new tablecell(view);
if (j == getcolumncount()) {
lastrowcount = j;
j = 0;
hashmap<string, object> map = new hashmap<string, object>();
tablerow tr = new tablerow(cell);
map.put("tablerow", tr);
tablerowslist.add(map);
layout = new linearlayout(getcontext());
addlayout(layout, cell, tr.getsize(), tr);
} else if (i >= count - 1 && j > 0) {
addlayout(layout, cell, j, tr);
getcolumncount（）是一個屬性，表示可以從xml或者從代碼動态改變gridview 每列顯示的個數，屬性點的代碼為如下：
public gridviewext(context context, attributeset attrs) {
super(context, attrs);
int resouceid = -1;
typedarray typedarray = context.obtainstyledattributes(attrs,
r.styleable.gridviewext);
int n = typedarray.getindexcount();
for (int i = 0; i < n; i++) {
int attr = typedarray.getindex(i);
switch (attr) {
case r.styleable.gridviewext_columncount:
resouceid = typedarray.getint(
r.styleable.gridviewext_columncount, 0);
setcolumncount(resouceid);
break;
typedarray.recycle();
還有，還必須實作它的支援鍵盤的上下左右的焦點，下面的代碼将會提供該功能，但還必須配合activity 的操作，等下文再講述。效果是這樣的：
全部源碼為：

intent = new intent(intent.action_call_button);
} else {

.getlaunchintentforpackage(name[0].tostring());
context.startactivity(intent);
/**

public void uncheckpressed() {
if (checkcolumnid != -1 && checkrowid != -1) {
viewgroup view = (viewgroup) this.getchildat(checkrowid);
view.getchildat(checkcolumnid).setpressed(false);
每行顯示的layout檔案：
<linearlayout android:orientation="vertical"
android:background="@drawable/lessbtn" android:gravity="center"
android:layout_width="fill_parent" android:id="@+id/grid_layout"
android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">
<imageview android:id="@+id/btn_appicon"
android:layout_width="55dip" android:layout_height="55dip"></imageview>
<textview android:id="@+id/tv_name" android:layout_width="wrap_content"
android:textcolor="#030303" android:layout_height="wrap_content"></textview>
<textview android:id="@+id/folder" android:layout_width="wrap_content"
android:visibility="invisible" android:layout_height="wrap_content"></textview>
</linearlayout>
完成這一系列的編寫後，你就可以在xml直接寫或者在java檔案裡面new 出來，但注意要設定它每列顯示的個數。
