TextView hieght = wrap_content is not working

Question

I have a LinearLayout which contains a single TextView :

            <LinearLayout
                android:id="@+id/addTaskDescriptionLLId"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginStart="16dp"
                android:layout_marginEnd="16dp">
                <TextView
                    android:id="@+id/descriptionTextViewId"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:maxHeight="150dp"
                    android:hint="@string/abcd"
                    android:textColor="#A2A2A2"
                    android:ellipsize="end"
                    android:layout_margin="10dp"/>
            </LinearLayout>

I've also added a condition in java file and the condition is if the TextView has some text during opening the activity then it will be visible otherwise I used descriptionTextView.setVisibility(View.GONE);

Then I put some text in this textView by opening a dialog and onConfirm (clicking positive button of dialog) I did the following:

    @Override
    public void onConfirm(String description) {
        this.description = description;    //the string that I write in dialog
        descriptionLL.removeAllViews();    //parent LineanLayout of TextView
        descriptionLL.addView(descriptionTextView);
        descriptionTextView.setText(description);
        descriptionTextView.setVisibility(View.VISIBLE);
    }

But the TextView height doesn't remain wrap_content as I mentioned in xml file. I've also tried:

descriptionTextView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));

that also no working..Any solution?

I think the hint that you've specified in xml is causing the problem. Remove it, it might solve.
