安卓软键盘的自动弹起/隐藏

InputMethodManager imm = (InputMethodManager) getActivity()
.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);

InputMethodManager im = (InputMethodManager) v.getContext()
.getSystemService( Context.INPUT_METHOD_SERVICE );
if (im.isActive()){
im.hideSoftInputFromWindow(v.getApplicationWindowToken(), 0);
}

//一个例子，适用于切入页面即触发EditText
<activity
android:name="com.uustudio.unote.activity.NoteEditActivity"
android:label="@string/app_name"
android:configChanges="orientation|keyboardHidden|locale"
android:screenOrientation="portrait"
android:windowSoftInputMode="stateVisible|adjustPan" >
