圆角.png
注意
我这个自定义圆角WebView是在原作者上面进行了一波修改
<!--圆角WebView-->
<declare-styleable name="ProgressCornersWebView">
<attr name="leftTopCorner" format="boolean"></attr>
<attr name="rightTopCorner" format="boolean"></attr>
<attr name="leftBottomCorner" format="boolean"></attr>
<attr name="rightBottomCorner" format="boolean"></attr>
<!--圆角半径-->
<attr name="cornerRadius" format="dimension"></attr>
</declare-styleable>
leftTopCorner，rightTopCorner等控制是否圆角
<com.qianti.mall.widget.ProgressCornersWebView
android:id="@+id/webView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
app:leftTopCorner="true"
app:rightTopCorner="true"
app:cornerRadius="@dimen/dp_5"
android:layout_marginBottom="@dimen/dp_5"
android:layerType="software" />

public class CornersWebView extends WebView {
private int vWidth;
private int vHeight;
private int scrollX, scrollY = 0;
private boolean leftTopCorner, rightTopCorner, leftBottomCorner, rightBottomCorner;
private float[] radiusArray = {0f, 0f, 0f, 0f, 0f, 0f, 0f, 0f};
public CornersWebView(Context context) {
this(context, null);
}
public CornersWebView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public CornersWebView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
TypedArray typedArray = context.obtainStyledAttributes(attrs, R.styleable.ProgressCornersWebView);
leftTopCorner = typedArray.getBoolean(R.styleable.ProgressCornersWebView_leftTopCorner, false);
rightTopCorner = typedArray.getBoolean(R.styleable.ProgressCornersWebView_rightTopCorner, false);
leftBottomCorner = typedArray.getBoolean(R.styleable.ProgressCornersWebView_leftBottomCorner, false);
rightBottomCorner = typedArray.getBoolean(R.styleable.ProgressCornersWebView_rightBottomCorner, false);
int radius = (int) typedArray.getDimension(R.styleable.ProgressCornersWebView_cornerRadius, getResources().getDimensionPixelSize(R.dimen.dp_5));
if (leftTopCorner) {
radiusArray[0] = radius;
radiusArray[1] = radius;
}
if (rightTopCorner) {
radiusArray[2] = radius;
radiusArray[3] = radius;
}
if (leftBottomCorner) {
radiusArray[4] = radius;
radiusArray[5] = radius;
}
if (rightBottomCorner) {
radiusArray[6] = radius;
radiusArray[7] = radius;
}
typedArray.recycle();
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
vWidth = getMeasuredWidth();
vHeight = getMeasuredHeight();
}
@Override
protected void onDraw(Canvas canvas) {
scrollX = this.getScrollX();
scrollY = this.getScrollY();
Path path = new Path();
RectF rectF = new RectF(scrollX, scrollY, scrollX + vWidth, scrollY + vHeight);
path.addRoundRect(rectF,radiusArray, Path.Direction.CW);
canvas.clipPath(path);
super.onDraw(canvas);
}
}
radiusArray 存储着左上角，右上角是否圆角
使用
//关闭硬件加速
webView.setLayerType(View.LAYER_TYPE_SOFTWARE,null);
//设置透明色
webView.setBackgroundColor(Color.parseColor("#00000000"));
webView.setVerticalScrollBarEnabled(false); //垂直滚动条不显示
String html="";//Html标签
webView.loadDataWithBaseURL(null, getHtmlData(html), "text/html", "UTF-8", null);
private String getHtmlData(String bodyHTML){
String head = "<head>" +
"<meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0, user-scalable=no\"> " +
"<style> body{font-size:14px;} img{padding:0px,margin:0px;max-width:100px;max-height: 100px; width:auto; height:auto;}</style>" +
"</head>";
return "<html>" + head + "<body>" + bodyHTML + "</body></html>";
}
需要关闭硬件加速
