Android仿Win8界面开发

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

  super.onDraw(canvas); 
  if (isFirst) { 
   isFirst = false; 
   init(); 
  }

    | Paint.FILTER_BITMAP_FLAG)); 
 }

  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) {

     scale_handler.sendEmptyMessage(Scale_Handler_Message_Start); 
    } 
   } else {

    } else {

    } 
   } 
   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 (isSizeChanged) 
     scale_handler

   } else {

     if (!isActionMove && onclick != null) { 
      onclick.onClick(); 
     } 
    } 
    count--; 
    count--; 
    break;

    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);

  } else if (RolateY > 0 && rotateY != 0) {

   matrix.postTranslate(scaleX, vHeight); 
  } else if (RolateX < 0 && rotateX != 0) { 
   matrix.preTranslate(-0, -scaleY); 
   matrix.postTranslate(0, scaleY); 
  } else if (RolateY < 0 && rotateY != 0) {

  } 
  setImageMatrix(matrix); 
 } 
 
 private Handler scale_handler = new Handler() {

  private float s; 
  int count = 0; 
 
  @Override

     count = 0; 
     s = (float) Math.sqrt(Math.sqrt(minScale)); 
     beginScale(matrix, s); 
     scale_handler 
       .sendEmptyMessage(Scale_Handler_Message_Turning); 
    } 
    break;

    beginScale(matrix, s); 
    if (count < 4) {

 } 
 
 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。
