一、EditText使用

<EditText         android:id="@+id/quick_index_search_edit_text"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_marginLeft="23dp"         android:layout_gravity="center_vertical"          android:background="@null"         android:paddingLeft="15dp"         android:paddingRight="0dp"         android:textColor="@color/white"         android:imeOptions="actionSearch"         android:ellipsize="end"         android:inputType="text|textAutoComplete|textNoSuggestions"         android:singleLine="true"         android:ems="10" >

android:imeOptions="actionSearch"会出现搜索的情况。

点击“搜索”可能会出现跳变到换行符，要添加setOnEditorActionListener的响应。

Class A implements OnEditorActionListener {

@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {

return true;// 默认为return false

}

二、AlertDialog的常用法

AlertDialog.Builder builder = new AlertDialog.Builder(Launcher.this, AlertDialog.THEME_TRADITIONAL);builder.setTitle(R.string.dialog_align_icon_title);builder.setMessage(R.string.dialog_align_icon_content);builder.setPositiveButton(android.R.string.cancel, null);builder.setNegativeButton(android.R.string.ok, new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stubalignIcons();}});Dialog dlg = builder.create();dlg.setOnKeyListener(new DialogInterface.OnKeyListener() {@Overridepublic boolean onKey(DialogInterface dialog, int keyCode,KeyEvent event) {if (keyCode == KeyEvent.KEYCODE_HOME){isAlignIconDialogOpen = true;dialog.dismiss();return true;}return false;}}); dlg.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);  dlg.show();

dlg.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);

if (keyCode == KeyEvent.KEYCODE_HOME)用于对home键的监听。
