CardView介绍
CardView是Android 5.0系统引入的控件,相当于FragmentLayout布局控件然后添加圆角及阴影的效果;CardView被包装为一种布局,并且经常在ListView和RecyclerView的Item布局中,作为一种容器使用。CardView应该被使用在显示层次性的内容时;在显示列表或网格时更应该被选择,因为这些边缘可以使得用户更容易去区分这些内容。

public class MainActivity extends AppCompatActivity { private CardView cardView; @Override protected void onCreate(Bundle savedInstanceState) { super .onCreate(savedInstanceState); setContentView(R.layout.activity_main); cardView = (CardView)findViewById(R.id.cardView); cardView.setRadius( 8 ); //设置图片圆角的半径大小 cardView.setCardElevation( 8 ); //设置阴影部分大小 cardView.setContentPadding( 5 , 5 , 5 , 5 ); //设置图片距离阴影大小 } } |
