本文實例講述了Android開發實現ListView點擊展開收起效果。分享給大家供大家參考，具體如下：

廢話不說先上效果：

實際上這是采用一個ExpandableListView實現的

布局文件很簡單：

xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical"

tools:context=".MainActivity" >

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:text="請選擇您的類型："

android:textSize="30sp"

android:textColor="#ffffffff"

android:paddingLeft="5dp"

android:paddingTop="5dp"

android:paddingBottom="5dp"

android:background="#ff000000"/>

android:id="@+id/list"

android:layout_width="match_parent"

android:layout_height="match_parent">

然后就是具體實現：

這里主要是添加幾個必須的屬性 大多數方法不用重寫

參考我代碼中的位置稍加改動就行

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

//創建一個ExpandableListAdapter對象

final ExpandableListAdapter adapter = new ExpandableListAdapter() {

int[] logos = new int[]{

R.drawable.human1st,

R.drawable.human1st,

R.drawable.human2nd,

R.drawable.human3rd

};

private String[] humanTypes = new String[]{

"不是人","聰明人","普通人","我這樣的人"

};

private String[][] humans = new String[][]{

{"上仙","大神","荷蘭豬"},

{"超人","一般聰明人","假的聰明人"},

{"努力的人","快樂的普通人","苦逼的普通人"},

{"天才","傻逼","蠢萌"}

};

//獲得制定組的位置、指定子列表項處的字列表項數據

private TextView getTextView(){

AbsListView.LayoutParams layoutParams =

new AbsListView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,164);

TextView textView = new TextView(MainActivity.this);

textView.setLayoutParams(layoutParams);

textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.LEFT);

textView.setPadding(36,0,0,0);

textView.setTextSize(30);

return textView;

}

@Override

public void registerDataSetObserver(DataSetObserver observer) {

}

@Override

public void unregisterDataSetObserver(DataSetObserver observer) {

}

@Override

public int getGroupCount() {

return humanTypes.length;

}

@Override

public int getChildrenCount(int groupPosition) {

return humans[groupPosition].length;

}

//獲取制定組位置處的組數據

@Override

public Object getGroup(int groupPosition) {

return humanTypes[groupPosition];

}

@Override

public Object getChild(int groupPosition, int childPosition) {

return humans[groupPosition][childPosition];

}

@Override

public long getGroupId(int groupPosition) {

return groupPosition;

}

@Override

public long getChildId(int groupPosition, int childPosition) {

return childPosition;

}

@Override

public boolean hasStableIds() {

return true;

}

//該方法決定每個組選項的外觀

@Override

public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {

LinearLayout linearLayout = new LinearLayout(MainActivity.this);

linearLayout.setOrientation(LinearLayout.HORIZONTAL);

ImageView logo = new ImageView(MainActivity.this);

logo.setImageResource(logos[groupPosition]);

linearLayout.addView(logo);

TextView textView = getTextView();

textView.setText(getGroup(groupPosition).toString());

linearLayout.addView(textView);

// linearLayout.setMinimumHeight(50);

return linearLayout;

}

@Override

public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {

TextView textView = getTextView();

textView.setText(getChild(groupPosition,childPosition).toString());

return textView;

}

@Override

public boolean isChildSelectable(int groupPosition, int childPosition) {

return true;

}

@Override

public boolean areAllItemsEnabled() {

return false;

}

@Override

public boolean isEmpty() {

return false;

}

@Override

public void onGroupExpanded(int groupPosition) {

}

@Override

public void onGroupCollapsed(int groupPosition) {

}

@Override

public long getCombinedChildId(long groupId, long childId) {

return 0;

}

@Override

public long getCombinedGroupId(long groupId) {

return 0;

}

};

ExpandableListView expandableListView = (ExpandableListView) findViewById(R.id.list);

expandableListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {

@Override

public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {

Toast.makeText(MainActivity.this,"你是一個：" +

adapter.getChild(groupPosition,childPosition),Toast.LENGTH_SHORT).show();

return true;

}

});

expandableListView.setAdapter(adapter);

}

}

希望本文所述對大家Android程序設計有所幫助。
