带有键盘向上移动的编辑文本的底页
Bottomsheet with edit text moved up by keyboard
我有底部sheet 片段显示用户对他的评论的回答。在底部 sheet 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 sheet 位于键盘上方,顶部移至屏幕之外。但底部 sheet 应该在键盘打开时调整大小。
这是我的代码:

Activity 在清单中(此 activity 打开对话框)
<activity
android:name=".presentation.ui.category.CategoryDetailsActivity"
android:configChanges="locale|orientation|screenSize|keyboard"

android:windowTranslucentNavigation="true"
android:windowTranslucentStatus="true"
android:launchMode="singleTop"
android:screenOrientation="portrait"
android:theme="@style/AppTheme.Main.NoActionBar" />
我也把这段代码放到方法中 setupDialog
dialog.getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
及截图
从 here
得到了这个答案
因为我在我的一个项目中也遇到了同样的问题,
在 onCreateDialog
BottomSheetFragment
中使用这个
new KeyboardUtil(getActivity(), rootView);
通过使用下面的 class
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);
}
}
}
我最终通过以下代码得到了令人满意的结果:
在 BottomSheetFragment
的 setupDialog(dialog: Dialog, style: Int) 方法中使用这个
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
}
