EditText获取焦点自动弹出键盘，有需要的朋友可以参考下。

一般的EditText是这样的：

<EditText
android:id="@+id/edit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left|center_vertical"
android:imeOptions="actionDone"
/>

当点击EditText的时候会自动弹出输入法键盘，或者直接调用editText.requestFocus()使显示输入法键盘，

其中android:imeOptions指定了弹出键盘时右下角的按键的显示文字，未指定时默认为回车图标。

android:imeOptions="flagNoExtractUi" //使软键盘不全屏显示，只占用一部分屏幕 

同时,这个属性还能控件软键盘右下角按键的显示内容,默认情况下为回车键 

android:imeOptions="actionNone" //输入框右侧不带任何提示 

android:imeOptions="actionGo" //右下角按键内容为'开始' 

android:imeOptions="actionSearch" //右下角按键为放大镜图片，搜索 

android:imeOptions="actionSend" //右下角按键内容为'发送' 

android:imeOptions="actionNext" //右下角按键内容为'下一步' 

android:imeOptions="actionDone" //右下角按键内容为'完成'

详细使用见 http://blog.csdn.net/caiwenfeng_for_23/article/details/37900503
当然也需要对这个按键进行设置点击事件：

editText.setOnEditorActionListener(new OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
// do sth when pressed the enter key in the Soft InputMethod
}
});

但是在AlertDialog或这PoupWIndow的EditText当调用requestFocus()方法的时候却不会自动弹出键盘，

此时需要直接调用显示键盘命令，当editText获取焦点的时候。

editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
//pop.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
}
}
});

在必要的时候隐藏输入法界面：

//隐藏输入法界面
((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(input.getWindowToken(), 0);
