Android自定义Drawable---灵活多变的矩形背景

Android自定义Drawable—灵活多变的矩形背景

在安卓开发中，我们通常需要为不同的按钮设置不同的背景以实现不同的效果，有时还需要这些按钮根据实际情况进行变化。如果采用编写resource中xml文件的形式，就需要重复定义许多只有微小变动的资源文件。这使得整个工程的简洁性和可读性受到影响。本文将介绍一种基于java代码实现的矩形背景自定义工具，该工具是继承Drawable的基础上开发的，它具有如下功能：

1. 自定义矩形的内部填充颜色和边框颜色；
2. 自定义矩形四角的弧度，支持分别定义和整体定义；
3. 自定义矩形的阴影（颜色、宽度及位置）；
4. 自定义矩形的触摸水波纹效果（颜色、显示速度）；
5. 自定义矩形的边框宽度（按比例/按固定宽度），并可与ObjectAnimator配合实现动画效果

综合展示如下：

此外，设置一个Builder让自定义构建变得更容易：

public static class Builder{private FlexibleRectDrawable drawable;public Builder() {this.drawable = new FlexibleRectDrawable();}public static Builder create(){return new Builder();}public Builder setSolidFill(@ColorInt int color){this.drawable.setSolidColor(color);switch(this.drawable.getType()){case BORDER_ONLY:this.drawable.setType(RectType.BORDERED_BLOCK);break;case SOLID_BLOCK:case BORDERED_BLOCK:Log.i("DrawableBuilder","cover solid color");break;case NOT_DEFINED:this.drawable.setType(RectType.SOLID_BLOCK);break;default:}return this;}public Builder setStroke(float width,@ColorInt int color){this.drawable.setHasStroke(true);this.drawable.setStrokeColor(color);this.drawable.setStrokeWidth(width);switch(this.drawable.getType()){case BORDER_ONLY:case BORDERED_BLOCK:Log.i("DrawableBuilder","cover solid color");break;case SOLID_BLOCK:this.drawable.setType(RectType.BORDERED_BLOCK);break;case NOT_DEFINED:this.drawable.setType(RectType.BORDER_ONLY);break;default:}return this;}public Builder setShadow(float shadowRange,@ColorInt int color){this.drawable.setNeedShadow(true);this.drawable.setShadowRange(shadowRange);this.drawable.setShadowColor(color);return this;}public Builder setShadowOffset(float top, float bottom, float left, float right){if(!this.drawable.isNeedShadow())throw new IllegalArgumentException("必须先调用setShadow,再设置阴影位置");this.drawable.setOffsetTop(top);this.drawable.setOffsetBottom(bottom);this.drawable.setOffsetLeft(left);this.drawable.setOffsetRight(right);return this;}public Builder setShadowOffsetCenter(float offset){if(!this.drawable.isNeedShadow())throw new IllegalArgumentException("必须先调用setShadow,再设置阴影位置");this.drawable.setOffsetTop(offset);this.drawable.setOffsetBottom(offset);this.drawable.setOffsetLeft(offset);this.drawable.setOffsetRight(offset);return this;}public Builder setCorners(int radius,int corner_type){this.drawable.setRectRadius(radius);this.drawable.setCorners(corner_type);return this;}public Builder setRipple(int color, int speed_millisecond){this.drawable.setNeedRipple(true);int check = color >>24;if (check==-1)throw new IllegalArgumentException("ripple颜色必须具有透明色");this.drawable.setRippleColor(color);this.drawable.setMaxRippleAlpha(color>>24 & 0xFF);this.drawable.setRippleSpeed(speed_millisecond);return this;}public FlexibleRectDrawable build(){this.drawable.setupPainters();return this.drawable;}}

辅助函数：dp转px

public int dp2Px(float dpValue) {final float scale = getResources().getDisplayMetrics().density;return (int) (dpValue * scale + 0.5f);}

使用方法

1. 一个普通的圆角按钮

FlexibleRectDrawable drawable1 = FlexibleRectDrawable.Builder.create().setStroke(dp2Px(3), Color.parseColor("#4682B4")).setSolidFill(Color.parseColor("#DAA520")).setCorners(dp2Px(50), FlexibleRectDrawable.CORNER_ALL).build();
LinearLayout view1 = findViewById(R.id.frd_view1);
view1.setBackground(drawable1);

2. 一个带水波纹效果的按钮

实心/空心：

//实心按钮
FlexibleRectDrawable drawabled1 = FlexibleRectDrawable.Builder.create().setSolidFill(Color.parseColor("#4682B4")).setCorners(dp2Px(50), FlexibleRectDrawable.CORNER_ALL).setRipple(Color.parseColor("#22FFFFFF"),300).build();
//空心按钮
FlexibleRectDrawable drawable2 = FlexibleRectDrawable.Builder.create().setStroke(dp2Px(3), Color.parseColor("#4682B4")).setCorners(dp2Px(50), FlexibleRectDrawable.CORNER_ALL).setRipple(Color.parseColor("#22000000"),300).build();

3. 一个带阴影的按钮

实心/空心：

//空心
FlexibleRectDrawable drawabled2 = FlexibleRectDrawable.Builder.create().setStroke(dp2Px(3),Color.parseColor("#1E90FF")).setCorners(dp2Px(50), FlexibleRectDrawable.CORNER_ALL).setShadow(dp2Px(7), Color.parseColor("#fe00FFFF")).setShadowOffsetCenter(dp2Px(5)).build();
//实心
FlexibleRectDrawable drawable2 = FlexibleRectDrawable.Builder.create().setStroke(dp2Px(3), Color.parseColor("#4682B4")).setCorners(dp2Px(50), FlexibleRectDrawable.CORNER_ALL).setSolidFill(Color.parseColor("#FFFFFF")).setShadow(dp2Px(5), Color.parseColor("#FEA9A9A9")).setShadowOffsetCenter(dp2Px(5)).build();

4. 两个左右合并的按钮

布局文件(.xml)：

<LinearLayoutandroid:id="@+id/frd_view_d3"android:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"android:layout_margin="10dp"android:layout_below="@id/frd_view_d2"><Buttonandroid:id="@+id/frd_btn1"android:layout_width="0dp"android:layout_height="wrap_content"android:layout_weight="1"android:text="btn1"/><Buttonandroid:id="@+id/frd_btn2"android:layout_width="0dp"android:layout_height="wrap_content"android:layout_weight="1"android:text="btn2"android:textColor="@color/white"/></LinearLayout>

对应java代码：

FlexibleRectDrawable drawable_btn_left = FlexibleRectDrawable.Builder.create().setStroke(dp2Px(3),Color.parseColor("#1E90FF")).setSolidFill(Color.parseColor("#1E90FF")).setCorners(dp2Px(50), FlexibleRectDrawable.CORNER_HALF_LEFT).setRipple(Color.parseColor("#33000000"),300).build();
FlexibleRectDrawable drawable_btn_right = FlexibleRectDrawable.Builder.create().setStroke(dp2Px(3),Color.parseColor("#1E90FF")).setCorners(dp2Px(50), FlexibleRectDrawable.CORNER_HALF_RIGHT).setRipple(Color.parseColor("#33FFFFFF"),300).build();
Button btn_left = findViewById(R.id.frd_btn1);
btn_left.setBackground(drawable_btn_left);
Button btn_right = findViewById(R.id.frd_btn2);
btn_right.setBackground(drawable_btn_right);

5. 按固定宽度设置矩形边框

改变边框的宽度和颜色

private boolean on_view3 = false;
...FlexibleRectDrawable drawable3 = FlexibleRectDrawable.Builder.create().setStroke(dp2Px(3), Color.parseColor("#4682B4")).setSolidFill(Color.parseColor("#131313")).setCorners(dp2Px(50), FlexibleRectDrawable.CORNER_ALL).build();LinearLayout view3 = findViewById(R.id.frd_view3);
view3.setBackground(drawable3);view3.setOnClickListener(v -> {on_view3 = !on_view3;if(on_view3){drawable3.setStrokeColor(Color.RED);drawable3.setStrokeWidthVariable(dp2Px(5));}else{drawable3.setStrokeColor(Color.parseColor("#4682B4"));drawable3.setStrokeWidthVariable(dp2Px(3));}});

通过属性动画实现按钮状态切换

private boolean on_view5 = false;
...FlexibleRectDrawable drawabled5 = FlexibleRectDrawable.Builder.create().setStroke(dp2Px(3),Color.parseColor("#4682B4")).setSolidFill(Color.parseColor("#3CB371")).setCorners(dp2Px(5), FlexibleRectDrawable.CORNER_ALL).build();
LinearLayout viewd5 = findViewById(R.id.frd_view_d5);
viewd5.setBackground(drawabled5);
viewd5.setOnClickListener(v -> {on_view5 = !on_view5;if(on_view5){ObjectAnimator animator = new ObjectAnimator();animator.setTarget(drawabled5);animator.setPropertyName("strokeWidthVariable");animator.setDuration(1000);animator.setFloatValues(drawabled5.getStrokeWidthVariable(),dp2Px(300));animator.start();}else {ObjectAnimator animator = new ObjectAnimator();animator.setTarget(drawabled5);animator.setPropertyName("strokeWidthVariable");animator.setDuration(1000);animator.setFloatValues(drawabled5.getStrokeWidthVariable(),dp2Px(3));animator.start();}});

6. 按所占百分比设置矩形边框

private boolean on_view6 = false;
private float origin_percent = 0.0f;
...FlexibleRectDrawable drawabled6 = FlexibleRectDrawable.Builder.create().setStroke(dp2Px(3),Color.parseColor("#4682B4")).setCorners(dp2Px(5), FlexibleRectDrawable.CORNER_ALL).build();
LinearLayout viewd6 = findViewById(R.id.frd_view_d6);
viewd6.setBackground(drawabled6);
viewd6.setOnClickListener(v -> {on_view6 = !on_view6;if (on_view6) {origin_percent = drawabled6.getStrokeInPercent();ObjectAnimator animator = new ObjectAnimator();animator.setTarget(drawabled6);animator.setPropertyName("strokeInPercent");animator.setDuration(500);animator.setFloatValues(origin_percent, 1f);animator.start();}else {ObjectAnimator animator = new ObjectAnimator();animator.setTarget(drawabled6);animator.setPropertyName("strokeInPercent");animator.setDuration(500);animator.setFloatValues(drawabled6.getStrokeInPercent(), origin_percent);animator.start();}});
