[2] 一个简略的界面拖动切换效果类ScrollViewGroup

来源: 互联网发布时间: 2014-02-18

一个简单的界面拖动切换效果类ScrollViewGroup
网上找的一个简单的界面平滑切换类，我只改动了一点点代码。
该类不能循环切换！

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.GestureDetector;
import android.view.GestureDetector.OnGestureListener;
import android.view.MotionEvent;
import android.view.View;
import android.view.ViewConfiguration;
import android.view.ViewGroup;
import android.widget.Scroller;

public class ScrollViewGroup extends ViewGroup {

	private static final String TAG = "scroller";

	private Scroller scroller;

	private int currentScreenIndex;

	public int getCurrentScreenIndex() {
		return currentScreenIndex;
	}

	public void setCurrentScreenIndex(int currentScreenIndex) {
		this.currentScreenIndex = currentScreenIndex;
	}

	private GestureDetector gestureDetector;

	// 设置一个标志位，防止底层的onTouch事件重复处理UP事件
	private boolean fling;

	public ScrollViewGroup(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
		initView(context);
	}

	public ScrollViewGroup(Context context, AttributeSet attrs) {
		super(context, attrs);
		initView(context);
	}

	public ScrollViewGroup(Context context) {
		super(context);
		initView(context);
	}

	private void initView(final Context context) {
		this.scroller = new Scroller(context);

		this.gestureDetector = new GestureDetector(new OnGestureListener() {

			@Override
			public boolean onSingleTapUp(MotionEvent e) {
				return false;
			}

			@Override
			public void onShowPress(MotionEvent e) {
			}

			@Override
			public boolean onScroll(MotionEvent e1, MotionEvent e2,
					float distanceX, float distanceY) {
				if ((distanceX > 0 && currentScreenIndex < getChildCount() - 1)// 防止移动过最后一页
						|| (distanceX < 0 && getScrollX() > 0)) {// 防止向第一页之前移动
					scrollBy((int) distanceX, 0);
				}
				return true;
			}

			@Override
			public void onLongPress(MotionEvent e) {
			}

			@Override
			public boolean onFling(MotionEvent e1, MotionEvent e2,
					float velocityX, float velocityY) {
				Log.d(TAG, "min velocity >>>"
						+ ViewConfiguration.get(context).getScaledMinimumFlingVelocity()
						+ " current velocity>>" + velocityX);
				// 判断是否达到最小轻松速度，取绝对值的
				if (Math.abs(velocityX) > ViewConfiguration.get(context).getScaledMinimumFlingVelocity()) {
						if (velocityX > 0 && currentScreenIndex > 0) {//手指从左往右划
							Log.d(TAG, ">>>>fling to left");
							fling = true;
							scrollToScreen(currentScreenIndex - 1);
						} else if (velocityX < 0 && currentScreenIndex < getChildCount() - 1) {
							Log.d(TAG, ">>>>fling to right");
							fling = true;
							scrollToScreen(currentScreenIndex + 1);
						}
				}

				return true;
			}

			@Override
			public boolean onDown(MotionEvent e) {
				return false;
			}
		});
		
	}

	@Override
	protected void onLayout(boolean changed, int left, int top, int right,int bottom) {
		Log.d(TAG, ">>left: " + left + " top: " + top + " right: " + right
				+ " bottom:" + bottom);

		/**
		 * 设置布局，将子视图顺序横屏排列
		 */
		for (int i = 0; i < getChildCount(); i++) {
			View child = getChildAt(i);
			child.setVisibility(View.VISIBLE);
			child.measure(right - left, bottom - top);
			child.layout(0 + i * getWidth(), 0, getWidth() + i * getWidth(),
					getHeight());
		}
		
		//初始化显示第几个界面
		int delta = currentScreenIndex * getWidth() - getScrollX();
		scroller.startScroll(getScrollX(), 0, delta, 0, 0);
		invalidate();
	}

	@Override
	public void computeScroll() {
		if (scroller.computeScrollOffset()) {
			scrollTo(scroller.getCurrX(), 0);
			postInvalidate();
		}
	}

	@Override
	public boolean onTouchEvent(MotionEvent event) {
		gestureDetector.onTouchEvent(event);

		switch (event.getAction()) {
		case MotionEvent.ACTION_DOWN:
			break;
		case MotionEvent.ACTION_MOVE:
			break;
		case MotionEvent.ACTION_UP:
			if (!fling) {
				snapToDestination();
			}
			fling = false;
			break;
		default:
			break;
		}
		return true;
	}

	/**
	 * 切换到指定屏
	 * 
	 * @param whichScreen
	 */
	private void scrollToScreen(int whichScreen) {
		if (getFocusedChild() != null && whichScreen != currentScreenIndex
				&& getFocusedChild() == getChildAt(currentScreenIndex)) {
			getFocusedChild().clearFocus();
		}

		final int delta = whichScreen * getWidth() - getScrollX();
		scroller.startScroll(getScrollX(), 0, delta, 0, Math.abs(delta) * 2);
		invalidate();

		currentScreenIndex = whichScreen;
		if (onScreenChangeListener != null) {
			onScreenChangeListener.onScreenChange(currentScreenIndex);
		}
	}

	/**
	 * 根据当前x坐标位置确定切换到第几屏
	 */
	private void snapToDestination() {
		scrollToScreen((getScrollX() + (getWidth() / 2)) / getWidth());
	}

	public interface OnScreenChangeListener {
		void onScreenChange(int currentIndex);
	}
	private OnScreenChangeListener onScreenChangeListener;

	public void setOnScreenChangeListener(OnScreenChangeListener onScreenChangeListener) {
		this.onScreenChangeListener = onScreenChangeListener;
	}
}

三个切换小点：

import com.easymorse.scroll.ScrollViewGroup.OnScreenChangeListener;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ImageView;
import android.widget.LinearLayout;

public class PageControlView extends LinearLayout {
	private Context context;

	private int count;

	public void bindScrollViewGroup(ScrollViewGroup scrollViewGroup) {
		this.count=scrollViewGroup.getChildCount();
		generatePageControl(scrollViewGroup.getCurrentScreenIndex());
		
		scrollViewGroup.setOnScreenChangeListener(new OnScreenChangeListener() {
			
			@Override
			public void onScreenChange(int currentIndex) {
				// TODO Auto-generated method stub
				generatePageControl(currentIndex);
			}
		});
	}

	public PageControlView(Context context) {
		super(context);
		this.init(context);
	}
	public PageControlView(Context context, AttributeSet attrs) {
		super(context, attrs);
		this.init(context);
	}

	private void init(Context context) {
		this.context=context;
	}

	private void generatePageControl(int currentIndex) {
		this.removeAllViews();

		for (int i = 0; i < this.count; i++) {
			ImageView imageView = new ImageView(context);
			if (currentIndex == i) {
				imageView.setImageResource(R.drawable.page_indicator_focused);
			} else {
				imageView.setImageResource(R.drawable.page_indicator);
			}
			this.addView(imageView);
		}
	}
}

用法：

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.ImageView;

public class ScrollDemosActivity extends Activity {

	@SuppressWarnings("unused")
	private static final String TAG = "scroller";

	private ScrollViewGroup viewGroup;

	private PageControlView pageControl;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);

		setContentView(R.layout.main);
		viewGroup = (ScrollViewGroup) findViewById(R.id.scrollViewGroup);

		ImageView imageView = new ImageView(this);
		imageView.setImageDrawable(getResources().getDrawable(R.drawable.a1));
		viewGroup.addView(imageView);

		viewGroup.addView(View.inflate(this, R.layout.layout_0, null));

		imageView = new ImageView(this);
		imageView.setImageDrawable(getResources().getDrawable(R.drawable.a2));
		viewGroup.addView(imageView);

		viewGroup.setCurrentScreenIndex(2);
		
		pageControl=(PageControlView) findViewById(R.id.pageControl);
		pageControl.bindScrollViewGroup(viewGroup);
		
	}
	
}

布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" 
	android:layout_width="fill_parent"

为什么动态布局只显示左上角啊

[3] 过程ID

进程ID

获取ID

Runtime r = Runtime.getRuntime();
            java.lang.Process p = r.exec("ps");
            BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
            String inline;
            while ((inline = br.readLine()) != null) {
                if (inline.endsWith(packageName)) {
                    break;
                }
            }
            br.close();
            StringTokenizer processInfoTokenizer = new StringTokenizer(inline);
            int count = 0;
            while (processInfoTokenizer.hasMoreTokens()) {
                count++;
                processId = processInfoTokenizer.nextToken();
                if (count == 2) {
                    break;
                }
            }
            r.exec("kill -15 " + processId);
