本文实例讲述了Android编程自定义搜索框实现方法。分享给大家供大家参考，具体如下：

先来看效果图吧~

分析：这只是模拟了一个静态数据的删除与显示

用EditText+PopupWindow+listView实现的

步骤：

1.先写出搜索框来-activity_mian布局：

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

android:layout_width="match_parent"

android:layout_height="match_parent"

>

android:id="@+id/et"

android:layout_width="match_parent"

android:layout_height="wrap_content"

/>

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:id="@+id/click"

android:layout_alignParentRight="true"

android:src="@drawable/down_arrow"/>

效果：

2.数据的加载，把数据写在ArrayList数组中，然后用适配器加载出来~

data=new ArrayList();

for(int i=0;i<20;i++){

data.add("1000"+i);

}

list.setAdapter(new MyAdapter());

3.点击箭头出现数据，在EditText搜索框下面出现，用PopupWindow实现~

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

switch (v.getId()) {

case R.id.click:

//if(popup==null){

/*TextView tv=new TextView(this);

tv.setText("123243");*/

list.setAdapter(new MyAdapter());

popup=new PopupWindow(list, et.getWidth(), 500);

popup.setFocusable(true);

//点击屏幕以外的区域会关掉

popup.setOutsideTouchable(true);

popup.setBackgroundDrawable(new ColorDrawable());

//显示在哪个控件的下面

popup.showAsDropDown(et);

// }else{

// popup=null;

//}

break;

default:

break;

}

}

4.listview适配器加载数据并且点击清除数据的图片，数据会消失：

class MyAdapter extends BaseAdapter{

@Override

public int getCount() {

// TODO Auto-generated method stub

if(data!=null){

return data.size();

}else {

return 0;

}

}

@Override

public Object getItem(int position) {

// TODO Auto-generated method stub

return null;

}

@Override

public long getItemId(int position) {

// TODO Auto-generated method stub

return 0;

}

@Override

public View getView(int position, View convertView, ViewGroup parent) {

// TODO Auto-generated method stub

View view=View.inflate(MainActivity.this, R.layout.listview, null);

TextView tv=(TextView) view.findViewById(R.id.tv);

ImageView iv=(ImageView) view.findViewById(R.id.iv);

text=data.get(position);

tv.setText(text);

iv.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

data.remove(text);

notifyDataSetChanged();

}

});

return view;

}

}

5.listview的点击,PopupWindow的消失,EditText数据的显示：

list.setOnItemClickListener(new OnItemClickListener() {

@Override

public void onItemClick(AdapterView> parent, View view, int position, long id) {

// TODO Auto-generated method stub

et.setText(text);

et.setSelection(text.length());//光标在text的后面

//PopupWindow消失

popup.dismiss();

}

});

这样就实现了自定义搜索框~

完整MainActivity：

public class MainActivity extends Activity implements OnClickListener{

private ImageView click;

private EditText et;

private PopupWindow popup;

ListView list;

Listdata;

String text;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

et=(EditText) findViewById(R.id.et);

click=(ImageView) findViewById(R.id.click);

click.setOnClickListener(this);

list=new ListView(this);

list.setOnItemClickListener(new OnItemClickListener() {

@Override

public void onItemClick(AdapterView> parent, View view, int position, long id) {

// TODO Auto-generated method stub

et.setText(text);

et.setSelection(text.length());//光标在text的后面

//PopupWindow消失

popup.dismiss();

}

});

data=new ArrayList();

for(int i=0;i<20;i++){

data.add("1000"+i);

}

}

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

switch (v.getId()) {

case R.id.click:

//if(popup==null){

/*TextView tv=new TextView(this);

tv.setText("123243");*/

list.setAdapter(new MyAdapter());

popup=new PopupWindow(list, et.getWidth(), 500);

popup.setFocusable(true);

//点击屏幕以外的区域会关掉

popup.setOutsideTouchable(true);

popup.setBackgroundDrawable(new ColorDrawable());

//显示在哪个控件的下面

popup.showAsDropDown(et);

// }else{

// popup=null;

//}

break;

default:

break;

}

}

class MyAdapter extends BaseAdapter{

@Override

public int getCount() {

// TODO Auto-generated method stub

if(data!=null){

return data.size();

}else {

return 0;

}

}

@Override

public Object getItem(int position) {

// TODO Auto-generated method stub

return null;

}

@Override

public long getItemId(int position) {

// TODO Auto-generated method stub

return 0;

}

@Override

public View getView(int position, View convertView, ViewGroup parent) {

// TODO Auto-generated method stub

View view=View.inflate(MainActivity.this, R.layout.listview, null);

TextView tv=(TextView) view.findViewById(R.id.tv);

ImageView iv=(ImageView) view.findViewById(R.id.iv);

text=data.get(position);

tv.setText(text);

iv.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

data.remove(text);

notifyDataSetChanged();

}

});

return view;

}

}

}

listview布局：

android:layout_width="match_parent"

android:layout_height="match_parent"

>

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:src="@drawable/user"/>

android:id="@+id/tv"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginLeft="100dp"/>

android:id="@+id/iv"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignParentRight="true"

android:src="@drawable/delete"/>
