问题
I am trying to have textviews overlay over imageviews. Something like this
Can someone help me with the code.
回答1:
I had the same problem and solved it using a custom gridView. You must apply this in getView.
Custom gridView XML:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_practitioner"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/item_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:contentDescription="@string/contentDescriptionContent"
/>
<LinearLayout
android:id="@+id/layout_login"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_gravity="center"
android:background="#CC515116"
android:visibility="gone"
android:gravity="center" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@android:color/white"
android:text="@string/text_enter_pass_password"
android:paddingBottom="7dp"
android:textSize="20sp"
/>
<EditText
android:id="@+id/edit_practitioner_pin"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_gravity="center"
android:background="@drawable/edittext_shape"
android:ems="6"
android:gravity="center"
android:inputType="numberPassword"
android:maxLength="4"
android:layout_marginBottom="10dp"
android:layout_marginTop="10dp"
android:visibility="visible"
/>
<Button
android:id="@+id/pract_button"
android:layout_width="70dp"
android:layout_height="30dp"
android:background="@drawable/buton_shape"
android:layout_marginBottom="35dp"
android:text="@string/btn_ok"
/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="bottom"
android:background="#bbffffff"
android:focusable="false"
android:focusableInTouchMode="false" >
<TextView android:id="@+id/item_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="3dp"
android:textColor="@color/text_black"
android:gravity="bottom|center"
android:textSize="20sp"
android:textAllCaps="true"
android:paddingBottom="0dp"
/>
<TextView
android:id="@+id/text_pratiotioner_group_name"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textColor="@color/sub_title_color"
android:visibility="visible"
android:gravity="bottom|center"
android:textAllCaps="true"
/>
</LinearLayout>
</FrameLayout>
回答2:
Wrap a TextView and ImageView into FrameLayout, put the TextView in FrameLayout after ImageView. Then, wrap the FrameLayout into RelativeLayout OR LinearLayout. Make some position setup (as per the needs).
<RelativeLayout>
<FrameLayout>
<ImageView />
<TextView />
</FrameLayout>
</RelativeLayout>

You can create a frame layout and within the frame layout keep an imageview and a linearlayout(with a translucent background and a textview).
The translucent color can be placed in the colors file as : #80000000 Here is a snippet :)
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainlayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:foregroundGravity="bottom"
android:orientation="vertical" >
<ImageView
android:id="@+id/ivFullScreenAd"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginBottom="8dp"
android:src="@drawable/home_page_ad" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="@color/translucent"
android:orientation="vertical" >
<TextView
android:id="@+id/detailTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:paddingLeft="10dip"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Please swipe up"
android:textColor="@color/white"
android:textIsSelectable="true"
android:textSize="20sp" />
</LinearLayout>
</FrameLayout>

Though an old question but should incase anyone is interested in the card view version of this question here you go...
<android.support.v7.widget.CardView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:cardCornerRadius="5dp"
app:cardElevation="5dp"
android:layout_weight="0.5"
app:cardPreventCornerOverlap="false"
app:cardUseCompatPadding="true"
android:clickable="true">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center_vertical"
android:layout_centerInParent="true">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:background="#89969F">
<ImageView
android:id="@+id/iv_overlay"
android:layout_width="196dp"
android:layout_height="196dp"
android:clickable="true"
android:src="@drawable/your_image"
android:layout_centerInParent="true" />
</RelativeLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#80000000"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:textSize="22sp"
android:textStyle="bold"
android:gravity="center_vertical"
android:text="Settings"
android:textColor="@color/white"
android:layout_gravity="center"
android:layout_alignParentTop="false"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:padding="8dp" />
</LinearLayout>
</FrameLayout>
</android.support.v7.widget.CardView>

Please modify the layout accordingly, If you want to accommodate the images on an imageview only, then you can drop the below layout in a relative one including an imageview too.
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/your_image"
android:orientation="vertical" >
<TextView
android:id="@+id/bottom_textview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
<!-- layout_gravity="supply accordingly" -->
android:gravity="center"/>
</LinearLayout>
