popupWindow自定义(1)
popupWindow自定义(2)
首先看看效果图：
动画拍的不是太好，将就着看看吧，就是在输入密码错误的时候加上了，密码左右抖动，状态栏变红警告
更新：
1、背景-磨砂玻璃
2、密码框错误动画
一、毛玻璃背景实现
原理很简单，就是获取屏幕截图后，做个磨砂处理
获取背景图片：
private Bitmap blur() {
if (null != overlay) {
return overlay;
}
long startMs = System.currentTimeMillis();
View view = mContext.getWindow().getDecorView();
view.setDrawingCacheEnabled(true);
view.buildDrawingCache(true);
mBitmap = view.getDrawingCache();
float scaleFactor = 10;// 图片缩放比例；
float radius = 50;// 模糊程度
int width = 0;
int height = 0;
if (mBitmap != null) {
width = mBitmap.getWidth();
height = mBitmap.getHeight();
} else {
height = mContext.getResources().getDisplayMetrics().heightPixels;
width = mContext.getResources().getDisplayMetrics().widthPixels;
}
overlay = Bitmap.createBitmap((int) (width / scaleFactor),
(int) (height / scaleFactor), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(overlay);
canvas.scale(1 / scaleFactor, 1 / scaleFactor);
Paint paint = new Paint();
paint.setFlags(Paint.FILTER_BITMAP_FLAG);
canvas.drawBitmap(mBitmap, 0, 0, paint);
overlay = FastBlur.doBlur(overlay, (int) radius, true);
Log.e("", "blur time is:" + (System.currentTimeMillis() - startMs));
return overlay;
}
使用：
mMenuView.setBackgroundDrawable(new BitmapDrawable(mContext.getResources(),
blur()));
用到的工具FastBlur：
import android.graphics.Bitmap;
public class FastBlur {
public static Bitmap doBlur(Bitmap sentBitmap, int radius,
boolean canReuseInBitmap) {
Bitmap bitmap;
if (canReuseInBitmap) {
bitmap = sentBitmap;
} else {
bitmap = sentBitmap.copy(sentBitmap.getConfig(), true);
}
if (radius < 1) {
return (null);
}
int w = bitmap.getWidth();
int h = bitmap.getHeight();
int[] pix = new int[w * h];
bitmap.getPixels(pix, 0, w, 0, 0, w, h);
int wm = w - 1;
int hm = h - 1;
int wh = w * h;
int div = radius + radius + 1;
int r[] = new int[wh];
int g[] = new int[wh];
int b[] = new int[wh];
int rsum, gsum, bsum, x, y, i, p, yp, yi, yw;
int vmin[] = new int[Math.max(w, h)];
int divsum = (div + 1) >> 1;
divsum *= divsum;
int dv[] = new int[256 * divsum];
for (i = 0; i < 256 * divsum; i++) {
dv[i] = (i / divsum);
}
yw = yi = 0;
int[][] stack = new int[div][3];
int stackpointer;
int stackstart;
int[] sir;
int rbs;
int r1 = radius + 1;
int routsum, goutsum, boutsum;
int rinsum, ginsum, binsum;
for (y = 0; y < h; y++) {
rinsum = ginsum = binsum = routsum = goutsum = boutsum = rsum = gsum = bsum = 0;
for (i = -radius; i <= radius; i++) {
p = pix[yi + Math.min(wm, Math.max(i, 0))];
sir = stack[i + radius];
sir[0] = (p & 0xff0000) >> 16;
sir[1] = (p & 0x00ff00) >> 8;
sir[2] = (p & 0x0000ff);
rbs = r1 - Math.abs(i);
rsum += sir[0] * rbs;
gsum += sir[1] * rbs;
bsum += sir[2] * rbs;
if (i > 0) {
rinsum += sir[0];
ginsum += sir[1];
binsum += sir[2];
} else {
routsum += sir[0];
goutsum += sir[1];
boutsum += sir[2];
}
}
stackpointer = radius;
for (x = 0; x < w; x++) {
r[yi] = dv[rsum];
g[yi] = dv[gsum];
b[yi] = dv[bsum];
rsum -= routsum;
gsum -= goutsum;
bsum -= boutsum;
stackstart = stackpointer - radius + div;
sir = stack[stackstart % div];
routsum -= sir[0];
goutsum -= sir[1];
boutsum -= sir[2];
if (y == 0) {
vmin[x] = Math.min(x + radius + 1, wm);
}
p = pix[yw + vmin[x]];
sir[0] = (p & 0xff0000) >> 16;
sir[1] = (p & 0x00ff00) >> 8;
sir[2] = (p & 0x0000ff);
rinsum += sir[0];
ginsum += sir[1];
binsum += sir[2];
rsum += rinsum;
gsum += ginsum;
bsum += binsum;
stackpointer = (stackpointer + 1) % div;
sir = stack[(stackpointer) % div];
routsum += sir[0];
goutsum += sir[1];
boutsum += sir[2];
rinsum -= sir[0];
ginsum -= sir[1];
binsum -= sir[2];
yi++;
}
yw += w;
}
for (x = 0; x < w; x++) {
rinsum = ginsum = binsum = routsum = goutsum = boutsum = rsum = gsum = bsum = 0;
yp = -radius * w;
for (i = -radius; i <= radius; i++) {
yi = Math.max(0, yp) + x;
sir = stack[i + radius];
sir[0] = r[yi];
sir[1] = g[yi];
sir[2] = b[yi];
rbs = r1 - Math.abs(i);
rsum += r[yi] * rbs;
gsum += g[yi] * rbs;
bsum += b[yi] * rbs;
if (i > 0) {
rinsum += sir[0];
ginsum += sir[1];
binsum += sir[2];
} else {
routsum += sir[0];
goutsum += sir[1];
boutsum += sir[2];
}
if (i < hm) {
yp += w;
}
}
yi = x;
stackpointer = radius;
for (y = 0; y < h; y++) {
// Preserve alpha channel: ( 0xff000000 & pix[yi] )
pix[yi] = (0xff000000 & pix[yi]) | (dv[rsum] << 16)
| (dv[gsum] << 8) | dv[bsum];
rsum -= routsum;
gsum -= goutsum;
bsum -= boutsum;
stackstart = stackpointer - radius + div;
sir = stack[stackstart % div];
routsum -= sir[0];
goutsum -= sir[1];
boutsum -= sir[2];
if (x == 0) {
vmin[y] = Math.min(y + r1, hm) * w;
}
p = x + vmin[y];
sir[0] = r[p];
sir[1] = g[p];
sir[2] = b[p];
rinsum += sir[0];
ginsum += sir[1];
binsum += sir[2];
rsum += rinsum;
gsum += ginsum;
bsum += binsum;
stackpointer = (stackpointer + 1) % div;
sir = stack[stackpointer];
routsum += sir[0];
goutsum += sir[1];
boutsum += sir[2];
rinsum -= sir[0];
ginsum -= sir[1];
binsum -= sir[2];
yi += w;
}
}
bitmap.setPixels(pix, 0, w, 0, 0, w, h);
return (bitmap);
}
}
二、动画实现
在监听最后一个输入框完成中处理：
if (isPassword（）) {//判断密码是否正确
//密码正确
pass.inputFinish();//接口中要实现的方法，完成密码输入完成后的响应逻辑
} else {
//密码错误
Animation shake = AnimationUtils.loadAnimation(mContext, R.anim.shake_left_right);//加载动画资源文件
password_layout.startAnimation(shake);
Utils.setStatusBarColor(mContext, R.color.red_transport);
shake.setAnimationListener(new Animation.AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
//动画结束之后
mStringPassword = "";
currentIndex = -1;
for (int i = 0; i < 6; i++) {
mTextViewPsw[i].setText("");
mTextViewPsw[i].setBackgroundResource(R.drawable.bg_circle_num_pwd);
}
warn.setVisibility(View.GONE);
Utils.setStatusBarColor(mContext, R.color.colorPrimary);
}
@Override
public void onAnimationRepeat(Animation animation) {
}
});
}
动画shake_left_right
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="20"
android:toXDelta="40"
android:duration="500"
android:interpolator="@anim/cycle_7" />
动画重复次数cycle_7
<?xml version="1.0" encoding="utf-8"?>
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android"
android:cycles="4"
/>
到此两种都实现了 _
