[1]Athrun框架自定义控件的施用

来源: 互联网发布时间: 2014-02-18

Athrun框架自定义控件的使用

无论Android还是iOS都支持自定义控件，而原始Athrun框架只支持系统控件，所以在使用Athrun框架进行功能自动化测试时需要根据项目的实际情况，自行扩展Athrun框架并添加项目中自定义控件的映射。如以下示例所示。

1 带有自定义控件的小应用：TestCustom。

其中

CustomTextView.java

package com.example.testcustom;

import android.content.Context;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.TextView;

public class CustomTextView extends TextView{

public CustomTextView(Context context, AttributeSet attrs) {
  super(context, attrs);
  setText("Custom");
  Drawable draw = getResources().getDrawable(R.drawable.huangqinbg);
  this.setCompoundDrawablesWithIntrinsicBounds(draw, draw, draw, draw);
  setBackgroundResource(R.drawable.huangqinbg);
}

public CustomTextView(Context context) {
  super(context);
  setText("Custom");
  Drawable draw = getResources().getDrawable(R.drawable.huangqinbg);
  this.setCompoundDrawablesWithIntrinsicBounds(draw, draw, draw, draw);
  setBackgroundResource(R.drawable.huangqinbg);
}
}

DrawGraphics.java

package com.example.testcustom;

import android.graphics.Canvas;

public interface DrawGraphics {
public void draw(Canvas canvas);
}

GameView.java

package com.example.testcustom;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.RectF;
import android.util.AttributeSet;
import android.view.View;

public class GameView extends View implements Runnable {
private Paint mPaint = null;
private DrawGraphics drawGraphics = null;
private static int mCircleColor = Color.GREEN;
private static int mLineColor = Color.GREEN;
private static int mRectColor = Color.GREEN;

public GameView(Context context) {

  super(context);
  mPaint = new Paint();
  new Thread(this).start();
}

public GameView(Context context, AttributeSet attrs) {
  super(context, attrs);
  mPaint = new Paint();
  new Thread(this).start();
}

public void onDraw(Canvas canvas) {
  super.onDraw(canvas);

// 设置画布为黑色背景
// canvas.drawColor(Color.BLACK);

// 消除锯齿
mPaint.setAntiAlias(true);

// 设置图形为空心
mPaint.setStyle(Paint.Style.STROKE);

  // 绘制空心几何图形
  drawGraphics = new DrawCircle();
  drawGraphics.draw(canvas);
  drawGraphics = new DrawLine();
  drawGraphics.draw(canvas);
  drawGraphics = new DrawRect();
  drawGraphics.draw(canvas);
}

@Override
public void run() {
while (!Thread.currentThread().isInterrupted()) {

   try {
    Thread.sleep(1000);
   } catch (InterruptedException e) {
    Thread.currentThread().interrupt();
   }

   // 使用postInvalidate 可以直接在线程中更新界面
   postInvalidate();
  }
}

public void setCircleColor(int circleColor) {
  mCircleColor = circleColor;
}

public int getCircleColor() {
  return mCircleColor;
}

public void setLineColor(int lineColor) {
  mLineColor = lineColor;
}

public int getLineColor() {
  return mLineColor;
}

public void setRectColor (int rectColor) {
  mRectColor = rectColor;
}

public int getRectColor() {
  return mRectColor;
}

static class DrawCircle implements DrawGraphics {

private Paint paint = null;
private Paint paint_eye = null;

  public DrawCircle() {
   paint = new Paint();
   paint_eye = new Paint();
  }

@Override
public void draw(Canvas canvas) {

   // 绘制圆形(圆心x，圆心y，半径r，画笔p)
   paint_eye.setAntiAlias(true);
   paint.setAntiAlias(true);

RectF rectF = new RectF(120/2, 60/2, 370/2, 240/2);

paint_eye.setColor(Color.BLACK);
paint.setColor(mCircleColor);

   canvas.drawCircle(190/2, 110/2, 18/2, paint_eye);
   canvas.drawCircle(300/2, 110/2, 18/2, paint_eye);
   canvas.drawArc(rectF, 180, 180, true, paint);
  }
}

static class DrawLine implements DrawGraphics {

  private Paint paint = null;
  public DrawLine() {
   paint = new Paint();
  }

  @Override
  public void draw(Canvas canvas) {
   paint.setAntiAlias(true);

// 绘制直线
paint.setColor(mLineColor);

// 设置线条粗细
paint.setStrokeWidth(12);

   canvas.drawLine(120/2, 40/2, 170/2, 90/2, paint);
   canvas.drawLine(320/2, 90/2, 370/2, 40/2, paint);
  }
}

static class DrawRect implements DrawGraphics {

private Paint paint = null;

  public DrawRect() {
   paint = new Paint();
  }

  @Override
  public void draw(Canvas canvas) {
   RectF rectF1 = new RectF(120/2, 170/2, 370/2, 500/2);
   RectF rectF2 = new RectF(40/2, 150/2, 90/2, 400/2);
   RectF rectF3 = new RectF(390/2, 150/2, 440/2, 400/2);
   RectF rectF4 = new RectF(140/2, 520/2, 200/2, 650/2);
   RectF rectF5 = new RectF(290/2, 520/2, 350/2, 650/2);

   paint.setAntiAlias(true);

// 设置画笔颜色为BLUE
paint.setColor(mRectColor);

   // 在画布上绘制圆角矩形/圆弧/直线
   canvas.drawRoundRect(rectF1, 20/2, 20/2, paint);
   canvas.drawRoundRect(rectF2, 20/2, 20/2, paint);
   canvas.drawRoundRect(rectF3, 20/2, 20/2, paint);
   canvas.drawRoundRect(rectF4, 20/2, 20/2, paint);
   canvas.drawRoundRect(rectF5, 20/2, 20/2, paint);
  }
}
}

2 提取TestCustom中自定义控件CustomTextView、GameView文件，并以CustomView.jar形式导出。

右击TestCustom——选中Export，将弹出下图：

如图选中JAR file，单击Next，如下图所示：

注意：右框中的最好都处于不选状态，左框中的视实际情况而定，有时自定义控件中需要用到一些资源文件，则res目录中相应的资源文件必须选中。JAR file框中应填写该jar文件的保存完整路径及jar文件名，这里为G:\huangqin\CustomView.jar 。

一直单击Next，知道Finish。

3 将CustomView.jar拷贝到Athrun framework中的libs目录下。

4 根据TestCustom中自定义控件CustomTextView、GameView的定义，在framework添加相应的映射文件CustomViewElement、GameViewElement。

其中

CustomViewElement.java

package org.athrun.android.framework.viewelement;

import android.app.Instrumentation;
import android.view.View;
import com.example.testcustom.*;

public class CustomViewElement extends ViewElement{

private CustomTextView mCustomView;
protected CustomViewElement(Instrumentation inst, CustomTextView view) {
  super(inst, view);
  mCustomView = view;
}

public void clearText() {
  setText("");
}

public void setText(final String newText) {
  inst.waitForIdleSync();
  ViewUtils.scrollInToScreenIfNeeded(inst, mCustomView);
  inst.waitForIdleSync();
  inst.runOnMainSync(new Runnable() {

   @Override
   public void run() {
    mCustomView.setText(newText);
   }
  });
  inst.waitForIdleSync();
}

public String getText() {
  inst.waitForIdleSync();
  ViewUtils.scrollInToScreenIfNeeded(inst, mCustomView);
  inst.waitForIdleSync();
  return mCustomView.getText().toString();
}
}

GameViewElement.java

package org.athrun.android.framework.viewelement;

import android.app.Instrumentation;

import com.example.testcustom.*;

public class GameViewElement extends ViewElement{

private GameView mGameView = null;
protected GameViewElement(Instrumentation inst, GameView view) {
  super(inst, view);
  mGameView = view;
}

public void setCircleColor(final int circleColor) {
  inst.waitForIdleSync();
  inst.runOnMainSync(new Runnable() {

   @Override
   public void run() {
    mGameView.setCircleColor(circleColor);
   }
  });
}

public void setLineColor (final int lineColor) {
  inst.waitForIdleSync();
  inst.runOnMainSync(new Runnable() {

   @Override
   public void run() {
    mGameView.setLineColor(lineColor);
   }
  });
}

public void setRectColor (final int rectColor){
  inst.waitForIdleSync();
  inst.runOnMainSync(new Runnable() {

   @Override
   public void run() {
    mGameView.setRectColor(rectColor);
   }
  });
}
}

5 通过ant jar重新编译framework.jar 。

6 将编译好的framework.jar文件拷贝到测试程序TestAthrunCustomView的libs目录下。然后引用自定义控件的映射文件CustomViewElement、GameViewElement进行功能自动化测试。

其中

MainActivityTest.java

package com.dragon.android.pandaspacetest;

import org.athrun.android.framework.AthrunTestCase;
import org.athrun.android.framework.Test;
import org.athrun.android.framework.ViewOperation.Direction;
import org.athrun.android.framework.viewelement.AbsListViewElement;
import org.athrun.android.framework.viewelement.CustomViewElement;
import org.athrun.android.framework.viewelement.GameViewElement;
import org.athrun.android.framework.viewelement.ViewGroupElement;

import android.graphics.Color;

public class MainActivityTest extends AthrunTestCase{

public MainActivityTest() throws Exception {
  super("com.example.testcustom", "com.example.testcustom.MainActivity");
  AthrunTestCase.setMaxTimeToFindView(10000);
}

@Test
public void testWaitForActivity() throws Exception{
  assertEquals(true, this.getDevice().waitForActivity("MainActivity", 3000));
}

@Test
public void testSetText() throws Exception {


  CustomViewElement customView = this.findElementById("custome_view", CustomViewElement.class);
  customView.setText("Custom Successfully!");
  String result = customView.getText();
  assertEquals(result, "Custom Successfully!");
  assertNotSame(result, "Custom Failed!");
}

@Test
public void testSetGameViewLineColor() throws Exception {
  GameViewElement gameView = this.findElementById("game_view", GameViewElement.class);
  gameView.setCircleColor(Color.YELLOW);
  gameView.setRectColor(Color.RED);

}

}

[2] 对View DrawingCache的了解

对View DrawingCache的理解

View组件显示的内容可以通过cache机制保存为bitmap, 使用到的api有

void setDrawingCacheEnabled(boolean flag),
Bitmap getDrawingCache(boolean autoScale),
void buildDrawingCache(boolean autoScale),
void destroyDrawingCache()

我们要获取它的cache先要通过setDrawingCacheEnable方法把cache开启，然后再调用getDrawingCache方法就可以获得view的cache图片了。buildDrawingCache方法可以不用调用，因为调用getDrawingCache方法时，若果 cache没有建立，系统会自动调用buildDrawingCache方法生成cache。若果要更新cache, 必须要调用destoryDrawingCache方法把旧的cache销毁，才能建立新的。当调用setDrawingCacheEnabled方法设置为false, 系统也会自动把原来的cache销毁。

ViewGroup在绘制子view时，而外提供了两个方法

void setChildrenDrawingCacheEnabled(boolean enabled)
setChildrenDrawnWithCacheEnabled(boolean enabled)

setChildrenDrawingCacheEnabled方法可以使viewgroup里所有的子view开启cache,setChildrenDrawnWithCacheEnabled使在绘制子view时，若该子view开启了cache, 则使用它的cache进行绘制，从而节省绘制时间。获取cache通常会占用一定的内存，所以通常不需要的时候有必要对其进行清理，通过destroyDrawingCache或setDrawingCacheEnabled(false)实现。

[3] NSFileManager 资料应用

来源: 互联网发布时间: 2014-02-18

NSFileManager 文件应用

- (void)clearDisk
{
    dispatch_async(self.ioQueue, ^
    {
        [[NSFileManager defaultManager] removeItemAtPath:self.diskCachePath error:nil];
        [[NSFileManager defaultManager] createDirectoryAtPath:self.diskCachePath
                                  withIntermediateDirectories:YES
                                                   attributes:nil
                                                        error:NULL];
    });
}

- (void)cleanDisk
{
    dispatch_async(self.ioQueue, ^
    {
        NSDate *expirationDate = [NSDate dateWithTimeIntervalSinceNow:-self.maxCacheAge];
        NSDirectoryEnumerator *fileEnumerator = [[NSFileManager defaultManager] enumeratorAtPath:self.diskCachePath];
        for (NSString *fileName in fileEnumerator)
        {
            NSString *filePath = [self.diskCachePath stringByAppendingPathComponent:fileName];
            NSDictionary *attrs = [[NSFileManager defaultManager] attributesOfItemAtPath:filePath error:nil];
            if ([[[attrs fileModificationDate] laterDate:expirationDate] isEqualToDate:expirationDate])
            {
                [[NSFileManager defaultManager] removeItemAtPath:filePath error:nil];
            }
        }
    });
}

-(int)getSize
{
    int size = 0;
    NSDirectoryEnumerator *fileEnumerator = [[NSFileManager defaultManager] enumeratorAtPath:self.diskCachePath];
    for (NSString *fileName in fileEnumerator)
    {
        NSString *filePath = [self.diskCachePath stringByAppendingPathComponent:fileName];
        NSDictionary *attrs = [[NSFileManager defaultManager] attributesOfItemAtPath:filePath error:nil];
        size += [attrs fileSize];
    }
    return size;
}

- (int)getDiskCount
{
    int count = 0;
    NSDirectoryEnumerator *fileEnumerator = [[NSFileManager defaultManager] enumeratorAtPath:self.diskCachePath];
    for (NSString *fileName in fileEnumerator)
    {
        count += 1;
    }
    
    return count;
}
