如何在TableRow内以编程方式设置ImageView的宽度?我不想改变单元格的宽度,只想改变单元格内图像的宽度。
布局:(省略号是为了缩减代码)
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal">
<TableRow android:gravity="center_vertical">
<Button>...</Button>
<ImageView
android:id="@+id/fruit"
android:layout_width="120dp"
android:layout_height="44dp"
android:src="@drawable/apple"
android:scaleType="matrix"
></ImageView>
<Button>...</Button>
</TableRow>
<TableRow>...</TableRow>
</TableLayout>
Java:
ImageView iv = (ImageView) findViewById(R.id.fruit);
LayoutParams frame = iv.getLayoutParams();
frame.width = 100;
iv.setLayoutParams(frame);
编辑: 我希望图片能够在我设置的边界内裁剪,并且表格单元格保留原始宽度。以下是代码示例,感谢parag的建议使其工作:
Bitmap bmp = BitmapFactory.decodeResource(getResources() , R.drawable.apple);
int width = 50;
int height = 44;
Bitmap resizedbitmap = Bitmap.createBitmap(bmp, iv.getScrollX(), iv.getScrollY(), width, height);
iv.setImageBitmap(resizedbitmap);
