本文介绍了一种在Android应用中创建自定义搜索对话框的方法。通过AlertDialog和LayoutInflater组件，可以弹出一个包含EditText输入框的对话框，允许用户输入搜索关键词，并通过Intent将搜索请求传递给另一个活动进行处理。

一、MainClass：
public void search(){
Builderdialog = new AlertDialog.Builder( this );
LayoutInflaterinflater = (LayoutInflater) this .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayoutlayout = (LinearLayout)inflater.inflate(R.layout.dialogview, null );
dialog.setView(layout);
et_search = (EditText)layout.findViewById(R.id.searchC);
dialog.setPositiveButton( " 查找 " , new DialogInterface.OnClickListener(){
public void onClick(DialogInterfacedialog, int which){
StringsearchC = et_search.getText().toString();
Intentintent = new Intent();
Bundlebundle = new Bundle();
bundle.putString( " search " ,searchC);
intent.putExtras(bundle);
intent.setClass(ViewResultActivity. this ,SearchResult. class );
ViewResultActivity. this .startActivity(intent);
}
});

dialog.setNegativeButton( " 取消 " , new DialogInterface.OnClickListener(){
public void onClick(DialogInterfacedialog, int which){

}

});
dialog.show();
}

二、dialogview.xml
<? xmlversion = " 1.0 " encoding = " utf-8 " ?>
< LinearLayoutxmlns:android = " http://schemas.android.com/apk/res/android "
android:orientation = " vertical "
android:layout_width = " fill_parent "
android:layout_height = " fill_parent "
>
< EditText
android:id = " @+id/searchC "
styles = " @style/edittext_style1 "
android:layout_width = " 200px "
android:layout_height = " wrap_content "
android:gravity = " left "
/>

</ LinearLayout >
