- 扩展 使用ViewHelper
View 中
public class TextViewExtension extends AppCompatTextView implements Checkable {
private ViewHelper mHelper = new ViewHelper();
public TextViewExtension(Context context) {
super(context);
mHelper.init(this);
}
public TextViewExtension(Context context, AttributeSet attrs) {
super(context, attrs);
mHelper.init(this, attrs);
}
public TextViewExtension(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
mHelper.init(this, attrs, defStyleAttr);
}
public ViewHelper<FrameLayoutExtension> getHelper() {
return mHelper;
}
@Override
protected void onAttachedToWindow() {
super.onAttachedToWindow();
mHelper.onAttachedToWindow(this);
}
@Override
protected void onDetachedFromWindow() {
super.onDetachedFromWindow();
mHelper.onDetachedFromWindow();
}
@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
mHelper.onSizeChanged(w, h);
}
@Override
public void draw(Canvas canvas) {
mHelper.saveLayer(canvas);
super.draw(canvas);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
mHelper.onClipDraw(canvas);
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
return mHelper.dispatchTouchEvent(ev) && super.dispatchTouchEvent(ev);
}
@Override
protected void drawableStateChanged() {
super.drawableStateChanged();
mHelper.drawableStateChanged();
}
@Override
public boolean isChecked() {
return mHelper.isChecked();
}
@Override
public void setChecked(boolean checked) {
mHelper.setChecked(checked);
}
@Override
public void toggle() {
setChecked(!mHelper.isChecked());
}
}
ViewGroup 中
public class FrameLayoutExtension extends FrameLayout implements Checkable {
private ViewHelper<FrameLayoutExtension> mHelper = new ViewHelper<>();
public FrameLayoutExtension(Context context) {
super(context);
mHelper.init(this);
}
public FrameLayoutExtension(Context context, AttributeSet attrs) {
super(context, attrs);
mHelper.init(this, attrs);
}
public FrameLayoutExtension(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
mHelper.init(this, attrs, defStyleAttr);
}
public ViewHelper<FrameLayoutExtension> getHelper() {
return mHelper;
}
@Override
protected void onAttachedToWindow() {
super.onAttachedToWindow();
mHelper.onAttachedToWindow(this);
}
@Override
protected void onDetachedFromWindow() {
super.onDetachedFromWindow();
mHelper.onDetachedFromWindow();
}
@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
mHelper.onSizeChanged(w, h);
}
@Override
public void draw(Canvas canvas) {
mHelper.saveLayer(canvas);
super.draw(canvas);
}
@Override
protected void dispatchDraw(Canvas canvas) {
mHelper.trySaveLayer(canvas);
super.dispatchDraw(canvas);
mHelper.onClipDraw(canvas);
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
return mHelper.dispatchTouchEvent(ev) && super.dispatchTouchEvent(ev);
}
@Override
protected void drawableStateChanged() {
super.drawableStateChanged();
mHelper.drawableStateChanged();
}
@Override
public boolean isChecked() {
return mHelper.isChecked();
}
@Override
public void setChecked(boolean checked) {
mHelper.setChecked(checked);
}
@Override
public void toggle() {
setChecked(!mHelper.isChecked());
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
return mHelper.onInterceptTouchEvent(ev) || super.onInterceptTouchEvent(ev);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
return mHelper.onTouchEvent(event) || super.onTouchEvent(event);
}
}
说明
由于阴影和模糊的特殊性，单独将ViewHelper进行封装；
ViewHelper 支持：设置范围是否包含Padding，默认true；是否只有设置范围内点击生效，默认false；是否是圆形，默认false；圆角设置；文本颜色设置；背景颜色、图设置；前景颜色、图设置；渐变色设置；边框设置；同时这些属性可以设置不同状态的值（默认、按下、选中、不可点击）；下拉关闭（用于ViewGroup，可实现微信朋友圈的图片查看器）；
- 使用阴影将不支持：前景图、背景图、边框、下拉关闭；
- 使用模糊将不支持：前景、背景、渐变、边框、下拉关闭；
