我有底部片段片段向用户回答他的评论。在底部的底部我们有编辑文本,用户可以在其中添加新评论。因此,当软键盘打开时,底部板位于键盘上方,其顶部远离屏幕。但是当键盘打开时,底部应该调整大小。
这是我的代码:

清单上的活动(此活动打开对话框)
<activity
android:name=".presentation.ui.category.CategoryDetailsActivity"
android:configChanges="locale|orientation|screenSize|keyboard"

android:windowTranslucentNavigation="true"
android:windowTranslucentStatus="true"

此外,我将此代码放入方法setupDialog
dialog.getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

从here
得到了这个答案正如我在其中一个项目中遇到同样的问题一样,
在BottomSheetFragment
中的onCreateDialog中使用它new KeyboardUtil(getActivity(), rootView);
使用以下课程
public class KeyboardUtil {
private View decorView;
private View contentView;
//a small helper to allow showing the editText focus
ViewTreeObserver.OnGlobalLayoutListener onGlobalLayoutListener = new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
//r will be populated with the coordinates of your view that area still visible.
decorView.getWindowVisibleDisplayFrame(r);
//get screen height and calculate the difference with the useable area from the r
int height = decorView.getContext().getResources().getDisplayMetrics().heightPixels;
int diff = height - r.bottom;
//if it could be a keyboard add the padding to the view
if (diff != 0) {
// if the use-able screen height differs from the total screen height we assume that it shows a keyboard now
//check if the padding is 0 (if yes set the padding for the keyboard)
if (contentView.getPaddingBottom() != diff) {
//set the padding of the contentView for the keyboard
contentView.setPadding(0, 0, 0, diff);
}
} else {
//check if the padding is != 0 (if yes reset the padding)
if (contentView.getPaddingBottom() != 0) {
//reset the padding of the contentView
contentView.setPadding(0, 0, 0, 0);
}
}
}
};
public KeyboardUtil(Activity act, View contentView) {
this.decorView = act.getWindow().getDecorView();
this.contentView = contentView;
//only required on newer android versions. it was working on API level 19
if (Build.VERSION.SDK_INT >= 19) {
decorView.getViewTreeObserver().addOnGlobalLayoutListener(onGlobalLayoutListener);
}
}
/**
* Helper to hide the keyboard
*
* @param act
*/
public static void hideKeyboard(Activity act) {
if (act != null && act.getCurrentFocus() != null) {
InputMethodManager inputMethodManager = (InputMethodManager) act.getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(act.getCurrentFocus().getWindowToken(), 0);
}
}
public void enable() {
if (Build.VERSION.SDK_INT >= 19) {
decorView.getViewTreeObserver().addOnGlobalLayoutListener(onGlobalLayoutListener);
}
}
public void disable() {
if (Build.VERSION.SDK_INT >= 19) {
decorView.getViewTreeObserver().removeOnGlobalLayoutListener(onGlobalLayoutListener);
}
}
}
答案 1 :(得分:3)
使用以下代码我最终获得了令人满意的结果: 在BottomSheetFragment中的setupDialog(dialog:Dialog,style:Int)方法中使用它
dialog.window?.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE)
dialog.setOnShowListener {
val bottomSheetDialog = dialog as BottomSheetDialog
val bottomSheet = bottomSheetDialog.findViewById<View>(android.support.design.R.id.design_bottom_sheet) as FrameLayout?
BottomSheetBehavior.from(bottomSheet!!).state = BottomSheetBehavior.STATE_EXPANDED
}
