java - textView.SetText 仅在文本较长时有效

Question

由于某些奇怪的原因，setText 仅在文本超过 600 个字符以上时才起作用...我从数据库中获取文本。

这是代码

private void renderViewDescription() {
    // reference

    final TextView descriptionTextView = (TextView) mRootView.findViewById(R.id.fragment_tour_detail_overview_text);
    // content
    Log.d("Overview: ",mTour.getOverview()); //Text is always ok
    descriptionTextView.setText(mTour.getOverview());
}

XML

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="@dimen/global_spacing_xxs"
            android:textAppearance="@style/TextAppearance.CityGuide.Headline"
            android:fontFamily="sans-serif-light"
            android:text="Overview" />

        <View
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="?attr/dividerHorizontal" />


        <TextView
            android:id="@+id/fragment_tour_detail_overview_text"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="@dimen/global_spacing_xxs"
            android:text="Body"
            android:textAppearance="@style/TextAppearance.CityGuide.Body1"
            android:textColor="@color/global_text_secondary"/>
        <View
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="?attr/dividerHorizontal" />


    </LinearLayout>
</android.support.v7.widget.CardView>

When text has many chars it works...

When it's below 500 - 600 it doesn't...

You need to remove the View from your Layout which is between both Text Views because it is overlapping your Body Text.

Also if you set android:layout_height="1dp" in your View here then it will work.

<TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:fontFamily="sans-serif-light"
            android:padding="10dp"
            android:singleLine="false"
            android:text="Overview"
            android:textAppearance="?attr/textAppearanceLargePopupMenu"
            android:textColor="#FFF" />

        <!--<View
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="?attr/dividerHorizontal" />-->

        <TextView
            android:id="@+id/fragment_tour_detail_overview_text"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="10dp"
            android:text="OverviewOverviewOverviewOverviewOverviewOverviewOverviewOverviewOverviewOverviewOverviewOverviewO"
            android:textAppearance="?attr/textAppearanceLargePopupMenu"
            android:textColor="#FFF" />
