如何以编程方式设置TableRow中ImageView的宽度?我不希望单元格宽度改变,只有单元格内部图像的宽度。Android:如何以编程方式设置ImageView的宽度TableRow
布局:(省略号是有减少的代码)
<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>
的Java:
ImageView iv = (ImageView) findViewById(R.id.fruit);
LayoutParams frame = iv.getLayoutParams();
frame.width = 100;
iv.setLayoutParams(frame);
编辑:我想被裁剪图像在我设置的边界内,并使表格单元成为原始宽度。下面是代码示例,由于parag的建议,对我有效:
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);
正是我所需要的 – keybee 2013-08-28 10:10:05
