在网格布局中使用ImageView显示文本

经过几天的努力,我终于能够让它发挥作用。我创建了一个XML文件,其中包含放在FrameLayout中的ImageView和TextView(在透明容器中):

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainlayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:foregroundGravity="bottom"
android:paddingBottom="2dp"
android:paddingLeft="2dp"
android:paddingRight="2dp"
android:paddingTop="2dp"
android:orientation="vertical" >

<ImageView
    android:id="@+id/ivFullScreenAd"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:contentDescription="@string/images_are_here"
    android:scaleType="centerCrop"
    android:src="@drawable/magric" />

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"
    android:background="#bbffffff"
    android:focusable="false"
    android:focusableInTouchMode="false"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/detailTitle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="3dp"
        android:gravity="bottom|center"
        android:paddingBottom="0dp"
        android:text="Please swipe up"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:textColor="@android:color/black"
        android:fontFamily="sans-serif-condensed"
        android:textStyle="bold"
        android:textSize="14sp" />
</LinearLayout>

然后我创建了“活动视图”,如下所示:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container_scroll_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="0dp"
android:paddingLeft="0dp"
android:paddingRight="0dp"
android:paddingTop="0dp"
tools:context="com.mtechcomm.mtechlifestyle.MenuScreenActivity">    
    <android.support.v7.widget.GridLayout
        android:id="@+id/menu_holder"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:fadingEdge="vertical"/>
 </ScrollView>

然后在“活动”中,我创建了GridLayout,如下所示:

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.widget.GridLayout;
import android.support.v7.widget.GridLayout.Spec;

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_menu_screen);

    gridLayout = (GridLayout) findViewById(R.id.menu_holder);

    gridLayout.setColumnCount(2);
    gridLayout.setRowCount(15);

    DisplayMetrics display = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics(display);

    int screenWidth = display.widthPixels;
    int screenHeight = display.heightPixels;
    int halfScreenWidth = (int) (screenWidth * 0.5);

    Spec row1 = GridLayout.spec(0, 2);
    Spec row2 = GridLayout.spec(2);
    Spec row3 = GridLayout.spec(3);
    Spec row4 = GridLayout.spec(4);
    Spec row5 = GridLayout.spec(5);
    Spec row6 = GridLayout.spec(6);
    Spec row7 = GridLayout.spec(7);

    Spec col0 = GridLayout.spec(0);
    Spec col1 = GridLayout.spec(1);
    Spec colspan2 = GridLayout.spec(0, 2);

但这可能不是最好的解决方案。
