如何在 Android 中的 ImageView 末尾添加 Text?

How to add Text in the end of ImageView in Android?

我有一个 ListFragment,我在 ListView 中使用 picasso 下载图像。这是我的 ArrayAdapter 代码:

 @Override
public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
    if (null == convertView) {
        convertView = inflater.inflate(R.layout.list_dish_view, parent, false);
    }

    DrawLineTransformationation myTransformation = new DrawLineTransformationation() {
        @Override
        public String key() {
            return super.key();
        }
    };


    Picasso
            .with(context)
            .load("http://i.imgur.com/rFLNqWI.jpg")
            .transform(myTransformation)
            .fit()
            .into((ImageView) convertView);
    return convertView;
}

private class DrawLineTransformationation implements Transformation {
    @Override
    public String key() {
        // TODO Auto-generated method stub
        return "drawline";
    }

    @Override
    public Bitmap transform(Bitmap bitmap) {
        // TODO Auto-generated method stub
        synchronized (DrawLineTransformationation.class) {
            if(bitmap == null) {
                return null;
            }
            Bitmap resultBitmap = bitmap.copy(bitmap.getConfig(), true);
            Bitmap bitmapImage = BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_heart);
            Canvas canvas = new Canvas(resultBitmap);
            Paint paint = new Paint();
            paint.setAntiAlias(true);
            paint.setColor(Color.WHITE);
            paint.setStyle(Paint.Style.FILL);
            paint.setTextSize(50);
            paint.setShadowLayer(2.0f, 1.0f, 1.0f, Color.BLACK);

            canvas.drawText("0", 10, 500, paint);
            canvas.drawBitmap(bitmapImage, 900, 20, null);
            bitmap.recycle();
            return resultBitmap;
        }
    }
}

list_dish_view.xml

<?xml version="1.0" encoding="utf-8"?>

<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/Roomimg"
    android:layout_width="match_parent"
    android:layout_height="200dp"/>

如果我运行上面的代码我可以看到这个view。 现在,我想在每个图像的末尾添加文本,并在右下角添加一个图像(这样一半是文字描述,另一半是大图像)。请参阅 this 示例。您可以在视图中看到文本和个人资料图片。我怎样才能实现我的情况?

尝试以下布局来实现您的设计。我在xml中使用了负边距,如果你想避免它,边距不能在计算后在activity中设置。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true"
        android:background="#FF000000"
        android:src="@drawable/matrix" />

    <TextView
        android:id="@+id/textView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/imageView"
        android:layout_centerHorizontal="true"
        android:background="#FFFF00FF"
        android:padding="10dp"
        android:text="Some text........." />

    <ImageView
        android:id="@+id/profilePic"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:layout_alignParentRight="true"
        android:layout_below="@id/imageView"
        android:layout_marginTop="-25dp"
        android:src="@drawable/circle" />
</RelativeLayout>
