PopupWindow 与 ActionBar 重叠

Question

I am using PopupWindow for show validation error with showAsDropDown(anchor).Validation Fields are validated by pressing the save button, so If anchor place under action bar, its popup overlaps actionBar. How do I fix this?

 protected void showPopup(View anchorPlace) {
    popupContainer.removeAllViews();
    popupContainer.addView(recyclerErrors);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        popupContainer.setElevation(0);
        anchorPlace.setElevation(0);
        popup.setElevation(0);
    }
    recyclerErrors.setOnClickListener(v -> dismissPopup());
    popup.setContentView(popupContainer);
    if (anchorPlace != null) {
        popup.setWidth(anchorPlace.getWidth());
    }
    popup.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
    popup.setOutsideTouchable(true);
    popup.setFocusable(false);
    popup.setTouchable(true);
    popup.setBackgroundDrawable(null);

    if (anchorPlace != null) {
        PopupWindowCompat.showAsDropDown(popup, anchorPlace, 0, 0, Gravity.BOTTOM);
    }

    if (popup.isAboveAnchor()) {
        popup.dismiss();
    }
}

Popup for validation error XML:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginStart="20dp"
    app:srcCompat="@drawable/warning_triangle" />

<TextView
    android:id="@+id/error_field_error_txt"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/warning_bcg"
    android:drawableStart="@drawable/ic_warning"
    android:drawablePadding="@dimen/settings_error_body_padding_top_bottom"
    android:gravity="center_vertical"
    android:paddingStart="@dimen/settings_error_body_padding_start_end"
    android:paddingTop="@dimen/settings_error_body_padding_top_bottom"
    android:paddingEnd="@dimen/settings_error_body_padding_start_end"
    android:paddingBottom="@dimen/settings_error_body_padding_top_bottom"
    android:textColor="@android:color/white"
    android:textSize="@dimen/settings_error_text_size"
    android:textStyle="bold"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"/></LinearLayout>

Answer 1

Try popup.setAttachedInDecor(true)

This will attach the popup window to the decor frame of the parent window to avoid overlaping with screen decorations like the navigation bar.

Also you may try using popup.setOverlapAnchor(false)

Sets whether the popup window should overlap its anchor view when displayed as a drop-down.

Hope it helps.

try to subtract both action and status bar height :

popup.setHeight(WindowManager.LayoutParams.WRAP_CONTENT - actionBarHeight - statusBarHeight);

my case, i created popupwindow programmatically with a FrameLayout parent.

PopupWindow popupWindow = new PopupWindow(frameLayout, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT - actionBarHeight - statusBarHeight);

Try these !

1st hide keyboard, so the top content will be visible.

public void hideSoftKeyboard(View view){
  InputMethodManager imm =(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
  imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

Then if you are using scrollview scroll to where (EditText/Other View) you want to show popup !

View targetView = findViewById(R.id.DESIRED_VIEW_ID);  
targetView.getParent().requestChildFocus(targetView,targetView);

在调用showPopup(...) editText.requestFocus()之前尝试调用editText.requestFocus()并让我知道它是否有效。
