本文将要模仿Win8界面的一个设计，一个一个的方块。方法很简单。这里自己把图片改改就可以成为自己想要的界面了。
1、首先来看看自定义的MyImageView：
package com.example.win8test; import android.annotation.SuppressLint; import android.content.Context; import android.graphics.Camera; import android.graphics.Canvas; import android.graphics.Matrix; import android.graphics.Paint; import android.graphics.PaintFlagsDrawFilter; import android.graphics.drawable.BitmapDrawable; import android.graphics.drawable.Drawable; import android.os.Handler; import android.os.Message; import android.util.AttributeSet; import android.view.MotionEvent; import android.widget.ImageView; @SuppressLint("HandlerLeak") public class MyImageView extends ImageView { public static final int Rotate_Handler_Message_Start = 1; public static final int Rotate_Handler_Message_Turning = 2; public static final int Rotate_Handler_Message_Turned = 3; public static final int Rotate_Handler_Message_Reverse = 6; public static final int Scale_Handler_Message_Start = 1; public static final int Scale_Handler_Message_Turning = 2; public static final int Scale_Handler_Message_Turned = 3; public static final int Scale_Handler_Message_Reverse = 6; private boolean isAntiAlias = true; private boolean scaleOnly = false; private boolean isSizeChanged = false; private boolean isShowAnimation = true; private int rotateDegree = 10; private boolean isFirst = true; private float minScale = 0.95f; private int vWidth; private int vHeight; private boolean isAnimationFinish = true, isActionMove = false, isScale = false; private Camera camera; boolean XbigY = false; float RolateX = 0; float RolateY = 0; OnViewClick onclick = null; public MyImageView(Context context) { super(context); camera = new Camera(); } public MyImageView(Context context, AttributeSet attrs) { super(context, attrs); camera = new Camera(); } public void SetAnimationOnOff(boolean oo) { isShowAnimation = oo; } public void setOnClickIntent(OnViewClick onclick) { this.onclick = onclick; } @SuppressLint("DrawAllocation") @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); if (isFirst) { isFirst = false; init(); } canvas.setDrawFilter(new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG | Paint.FILTER_BITMAP_FLAG)); } public void init() { vWidth = getWidth() - getPaddingLeft() - getPaddingRight(); vHeight = getHeight() - getPaddingTop() - getPaddingBottom(); Drawable drawable = getDrawable(); BitmapDrawable bd = (BitmapDrawable) drawable; bd.setAntiAlias(isAntiAlias); } @Override public boolean onTouchEvent(MotionEvent event) { super.onTouchEvent(event); if (!isShowAnimation) return true; switch (event.getAction() & MotionEvent.ACTION_MASK) { case MotionEvent.ACTION_DOWN: float X = event.getX(); float Y = event.getY(); RolateX = vWidth / 2 - X; RolateY = vHeight / 2 - Y; XbigY = Math.abs(RolateX) > Math.abs(RolateY) ? true : false; isScale = X > vWidth / 3 && X < vWidth * 2 / 3 && Y > vHeight / 3 && Y < vHeight * 2 / 3; isActionMove = false; if (isScale) { if (isAnimationFinish && !isSizeChanged) { isSizeChanged = true; scale_handler.sendEmptyMessage(Scale_Handler_Message_Start); } } else { if (scaleOnly) { scale_handler.sendEmptyMessage(Scale_Handler_Message_Start); } else { rotate_Handler .sendEmptyMessage(Rotate_Handler_Message_Start); } } break; case MotionEvent.ACTION_MOVE: float x = event.getX(); float y = event.getY(); if (x > vWidth || y > vHeight || x < 0 || y < 0) { isActionMove = true; } else { isActionMove = false; } break; case MotionEvent.ACTION_UP: if (isScale) { if (isSizeChanged) scale_handler .sendEmptyMessage(Scale_Handler_Message_Reverse); } else { rotate_Handler.sendEmptyMessage(Rotate_Handler_Message_Reverse); } break; } return true; } public interface OnViewClick { public void onClick(); } @SuppressLint("HandlerLeak") private Handler rotate_Handler = new Handler() { private Matrix matrix = new Matrix(); private float count = 0; // private boolean clickGuolv = false; @Override public void handleMessage(Message msg) { super.handleMessage(msg); matrix.set(getImageMatrix()); switch (msg.what) { case Rotate_Handler_Message_Start: count = 0; beginRotate(matrix, (XbigY ? count : 0), (XbigY ? 0 : count)); rotate_Handler.sendEmptyMessage(Rotate_Handler_Message_Turning); break; case Rotate_Handler_Message_Turning: beginRotate(matrix, (XbigY ? count : 0), (XbigY ? 0 : count)); count++; if (count < getDegree()) { rotate_Handler .sendEmptyMessage(Rotate_Handler_Message_Turning); } else { isAnimationFinish = true; } break; case Rotate_Handler_Message_Turned: beginRotate(matrix, (XbigY ? count : 0), (XbigY ? 0 : count)); if (count > 0) { rotate_Handler .sendEmptyMessage(Rotate_Handler_Message_Turned); } else { isAnimationFinish = true; if (!isActionMove && onclick != null) { onclick.onClick(); } } count--; count--; break; case Rotate_Handler_Message_Reverse: count = getDegree(); beginRotate(matrix, (XbigY ? count : 0), (XbigY ? 0 : count)); rotate_Handler.sendEmptyMessage(Rotate_Handler_Message_Turned); break; } } }; private synchronized void beginRotate(Matrix matrix, float rotateX, float rotateY) { // Bitmap bm = getImageBitmap(); int scaleX = (int) (vWidth * 0.5f); int scaleY = (int) (vHeight * 0.5f); camera.save(); camera.rotateX(RolateY > 0 ? rotateY : -rotateY); camera.rotateY(RolateX < 0 ? rotateX : -rotateX); camera.getMatrix(matrix); camera.restore(); // 控制中心点 if (RolateX > 0 && rotateX != 0) { matrix.preTranslate(-vWidth, -scaleY); matrix.postTranslate(vWidth, scaleY); } else if (RolateY > 0 && rotateY != 0) { matrix.preTranslate(-scaleX, -vHeight); matrix.postTranslate(scaleX, vHeight); } else if (RolateX < 0 && rotateX != 0) { matrix.preTranslate(-0, -scaleY); matrix.postTranslate(0, scaleY); } else if (RolateY < 0 && rotateY != 0) { matrix.preTranslate(-scaleX, -0); matrix.postTranslate(scaleX, 0); } setImageMatrix(matrix); } private Handler scale_handler = new Handler() { private Matrix matrix = new Matrix(); private float s; int count = 0; @Override public void handleMessage(Message msg) { super.handleMessage(msg); matrix.set(getImageMatrix()); switch (msg.what) { case Scale_Handler_Message_Start: if (!isAnimationFinish) { return; } else { isAnimationFinish = false; isSizeChanged = true; count = 0; s = (float) Math.sqrt(Math.sqrt(minScale)); beginScale(matrix, s); scale_handler .sendEmptyMessage(Scale_Handler_Message_Turning); } break; case Scale_Handler_Message_Turning: beginScale(matrix, s); if (count < 4) { scale_handler .sendEmptyMessage(Scale_Handler_Message_Turning); } else { isAnimationFinish = true; if (!isSizeChanged && !isActionMove && onclick != null) { onclick.onClick(); } } count++; break; case Scale_Handler_Message_Reverse: if (!isAnimationFinish) { scale_handler .sendEmptyMessage(Scale_Handler_Message_Reverse); } else { isAnimationFinish = false; count = 0; s = (float) Math.sqrt(Math.sqrt(1.0f / minScale)); beginScale(matrix, s); scale_handler .sendEmptyMessage(Scale_Handler_Message_Turning); isSizeChanged = false; } break; } } }; private synchronized void beginScale(Matrix matrix, float scale) { int scaleX = (int) (vWidth * 0.5f); int scaleY = (int) (vHeight * 0.5f); matrix.postScale(scale, scale, scaleX, scaleY); setImageMatrix(matrix); } public int getDegree() { return rotateDegree; } public void setDegree(int degree) { rotateDegree = degree; } public float getScale() { return minScale; } public void setScale(float scale) { minScale = scale; } }
2、下来，来看看布局
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/d" android:orientation="vertical" tools:context=".MainActivity" > <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal" > <com.example.win8test.MyImageView android:id="@+id/MyImageView01" android:layout_width="108dp" android:layout_height="108dp" android:layout_margin="16dp" android:scaleType="matrix" android:src="@drawable/fen" /> <com.example.win8test.MyImageView android:id="@+id/MyImageView02" android:layout_width="108dp" android:layout_height="108dp" android:layout_margin="16dp" android:scaleType="matrix" android:src="@drawable/fen" /> </LinearLayout> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal" > <com.example.win8test.MyImageView android:id="@+id/MyImageView03" android:layout_width="108dp" android:layout_height="108dp" android:layout_margin="16dp" android:scaleType="matrix" android:src="@drawable/fen" /> <com.example.win8test.MyImageView android:id="@+id/MyImageView04" android:layout_width="108dp" android:layout_height="108dp" android:layout_margin="16dp" android:scaleType="matrix" android:src="@drawable/fen" /> </LinearLayout> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal" > <com.example.win8test.MyImageView android:id="@+id/MyImageView05" android:layout_width="108dp" android:layout_height="108dp" android:layout_margin="16dp" android:scaleType="matrix" android:src="@drawable/fen" /> <com.example.win8test.MyImageView android:id="@+id/MyImageView06" android:layout_width="108dp" android:layout_height="108dp" android:layout_margin="16dp" android:scaleType="matrix" android:src="@drawable/fen" /> </LinearLayout> </LinearLayout>
3、上面的图片按钮的用法，这里只给一张图片按钮添加了事件：
MyImageView image_3D_1 = (MyImageView)findViewById(R.id.MyImageView01); image_3D_1.setOnClickIntent(new MyImageView.OnViewClick() { @Override public void onClick() { Toast.makeText(MainActivity.this, "clicked", 100) .show(); } });
4、效果
手指按在中间是缩小，手指按在边上是有角度的卷动
手指一直按着的时候，被按下的那个图像变小，并且手指一直按着移动，此时其它图片按钮不响应
希望本文所述对大家学习Android软件编程有所帮助。
