在android中在ImageView上显示TextView

2022-01-24 00:00:00 android android-layout java imageview textview

我想在图像视图上显示文本.我像 Alesqui 在这里建议的那样做:Android 文字覆盖图片

I want to display a text over an Image View. I do it like Alesqui suggested here: Android Text over image

Android Studio 中的预览看起来不错:

The preview in Android studio looks fine:

但我的实际结果看起来像这样，上面的文字不需要:

But my actual result looks like this with the text unwantedly above:

我必须在执行期间将以下 XML 动态添加到 LinearLayout:

I have to add the following XML dynamically to a LinearLayout during the execution:

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/relativelayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <ImageView
        android:id="@+id/myImageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/myImageSouce" />

    <TextView
        android:id="@+id/myImageViewText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/myImageView"
        android:layout_alignTop="@+id/myImageView"
        android:layout_alignRight="@+id/myImageView"
        android:layout_alignBottom="@+id/myImageView"
        android:layout_margin="1dp"
        android:gravity="center"
        android:text="Hello"
        android:textColor="#000000" />

</RelativeLayout>

我是这样添加的:

LinearLayout ll = (LinearLayout) findViewById(R.id.layout_story_covers);
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    for (int i = 0; i < stories.size(); i++)
    {
        // add  imageView
        RelativeLayout coverLayout = (RelativeLayout) inflater.inflate(R.layout.fragment_cover, null);
        ImageView imageView =(ImageView) coverLayout.findViewById(R.id.imageViewCover);
        TextView textView = (TextView) coverLayout.findViewById(R.id.textViewCover);
        textView.setText(stories.get(i).title);
        imageLoader.displayImage(stories.get(i).cover.fileUrl, imageView);
        ll.addView(coverLayout);
    }

这一定与那个父 LinearLayout 有关.获得结果的正确方法是什么?

This must have something to do with that parent LinearLayout. What is the proper way to do get the result?

推荐答案

试试这个:

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/relativelayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ImageView
        android:id="@+id/myImageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/myImageSouce" />

    <TextView
        android:id="@+id/myImageViewText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_margin="1dp"
        android:gravity="center"
        android:text="Hello"
        android:textColor="#000000" />

</RelativeLayout>
