我在Activity中的Fragment中有一个EditText.
我的活动布局：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/login_bg">
...
<FrameLayout
android:id="@+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
...
</RelativeLayout>
AndroidManifest.xml中的我的Activity配置：
<activity
android:name="com.demo.LoginActivity"
android:configChanges="orientation|keyboardHidden"
android:launchMode="singletop"
android:screenorientation="portrait"
android:theme="@style/activityTheme" />
用于在Activity中启动片段的代码：
private void startFragment(BaseFragment fragment,String tag) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.fragment_container,fragment);
fragmentTransaction.addToBackStack(tag);
fragmentTransaction.commitAllowingStateLoss();
}
我的片段布局：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/common_background_color_white"
android:orientation="vertical"
android:clickable="true"
android:paddingLeft="@dimen/email_common_padding_horizontal"
android:paddingRight="@dimen/email_common_padding_horizontal">
...
<com.example.widget.LineEditView
android:id="@+id/login_email_input"
style="@style/BaseEditText.LoginEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:focusable="true"
/>
...
</LinearLayout>
我的自定义小部件LineEditView是一个子类扩展RelativeLayout,它的布局：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/input"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="@+id/edit"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:focusable="true"
android:gravity="start|center_vertical"
android:background="@android:color/transparent"
android:textColor="@color/common_text_color_black"
android:maxLines="1"
android:textCursorDrawable="@drawable/common_cursor_background_orange"
android:textSize="@dimen/email_fields_text_size"
android:paddingBottom="@dimen/email_fields_text_padding_bottom"/>
<View
android:id="@+id/underline"
android:layout_below="@id/edit"
android:layout_width="match_parent"
android:layout_height="2px"/>
</RelativeLayout>
我想根据EditText的inputType属性显示软键盘,并且可以轻松隐藏.
我尝试过但不工作或不完美：
1.根据Show keyboard for edittext when fragment starts可以显示软键盘但不能轻易隐藏(有时甚至无法隐藏)并且它根据EditText的inputType属性显示键盘.
2.我将以下代码添加到My Fragment：
@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container) {
mEditText = (EditText) rootView.findViewById(R.id.edit);
mEditText.requestFocus();
mEditText.setFocusable(true);
}
@Override
public void onResume() {
mEditText.postDelayed(mShowSoftInputRunnable,400);
super.onResume();
}
private Runnable mShowSoftInputRunnable = new Runnable() {
@Override
public void run() {
FragmentActivity activity = getActivity();
if (activity == null)
return;
InputMethodManager input = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
input.showSoftInput(mEditText,InputMethodManager.SHOW_IMPLICIT);
}
};
但它在我的片段中根本无法显示软键盘.
我不能将EditText放到Activity中,因为它需要重构很多代码.
有没有人有想法解决这个问题？
解决方法
这是我使用的代码,它在Fragments中运行得非常好
public static void hideKeyboard(Context context) {
try {
((Activity) context).getwindow().setSoftInputMode(WindowManager.LayoutParams.soFT_INPUT_STATE_ALWAYS_HIDDEN);
if ((((Activity) context).getCurrentFocus() != null) && (((Activity) context).getCurrentFocus().getwindowToken() != null)) {
((InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(((Activity) context).getCurrentFocus().getwindowToken(),0);
}
} catch (Exception e) {
e.printstacktrace();
}
}
public static void showKeyboard(Context context) {
((InputMethodManager) (context).getSystemService(Context.INPUT_METHOD_SERVICE)).toggleSoftInput(InputMethodManager.SHOW_FORCED,InputMethodManager.HIDE_IMPLICIT_ONLY);
}
