Android 单击“上一步”按钮后键盘关闭时,如何从编辑文本中清除焦点?
我有一个Android 单击“上一步”按钮后键盘关闭时,如何从编辑文本中清除焦点?,android,android-edittext,Android,Android Edittext,我有一个AppBarLayout,当我触摸EditText时,我会隐藏起来 SearchFragment.class binding.searchEt.setOnFocusChangeListener { view, hasFocus -> if (hasFocus) { binding.appBarLayout.setExpanded(false, true) } else { binding.appBar
AppBarLayout
,当我触摸EditText
时,我会隐藏起来
SearchFragment.class
binding.searchEt.setOnFocusChangeListener { view, hasFocus ->
if (hasFocus) {
binding.appBarLayout.setExpanded(false, true)
} else {
binding.appBarLayout.setExpanded(true, true)
}
}
但当键盘关闭时,我无法再次显示AppBarLayout。因为当键盘关闭时,编辑文本的焦点不会改变
Xml
<EditText
android:id="@+id/searchEt"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginStart="8dp"
android:layout_toStartOf="@+id/close_button"
android:layout_toEndOf="@+id/ic_search"
android:background="@android:color/transparent"
android:focusable="true"
android:focusableInTouchMode="true"

android:hint="@string/search_hint"
android:imeOptions="actionSearch"
android:includeFontPadding="true"
android:orientation="vertical"
android:paddingStart="12dp"
android:singleLine="true"
android:textAlignment="viewStart"

键盘隐藏时如何清除焦点?键盘隐藏后光标仍显示。使用如下方式:
public void hideKeyboard(Activity activity){
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
View view = activity.getCurrentFocus();
if(view != null){
view.clearFocus();
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
使用类似以下内容:
public void hideKeyboard(Activity activity){
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
View view = activity.getCurrentFocus();
if(view != null){
view.clearFocus();
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
在键盘内部关闭侦听器,关闭键盘后清除editText中的焦点
editText.setFocusable(false);
editText.setFocusableInTouchMode(true);

editText.setFocusable(false);
editText.setFocusableInTouchMode(true);
