分享界面
为了方便以后开发和熟悉代码，小手亲自实现分享界面。为了减少过多的相关文件，界面使用代码实现，实现如下：

实现分享界面的代码（用到了两个自定义控件）

package cn.zszh.customs.widget.base; import android.app.Dialog; import android.content.Context; import android.util.DisplayMetrics; import android.view.KeyEvent;import android.view.View; import android.view.animation.Animation; import android.view.animation.Animation.AnimationListener;import android.view.animation.TranslateAnimation; public class BaseDialog extends Dialog{ public View mCreateView; public Context mContext; public int mScreenWidth;//屏幕宽 public int mScreenHeight;//屏幕高 public int mDensity;//单位像素 public Animation mExitAnim;//退出动画 public Animation mEnterAnim;//进入动画 public BaseDialog(Context context) { super(context); init(context); } private void init(Context context) { mContext=context; //计算屏幕的宽高像素 DisplayMetrics metrics=mContext.getResources().getDisplayMetrics(); mScreenHeight=metrics.heightPixels; mScreenWidth=metrics.widthPixels; mDensity=(int) metrics.density; } @Override public void show() { super.show(); enterAnimation();//进入动画 } /** * 进入动画 */ private void enterAnimation(){ if(mEnterAnim==null){ mEnterAnim=new TranslateAnimation(1, 0, 1, 0, 1, 1, 1, 0); mEnterAnim.setDuration(500); } mCreateView.startAnimation(mEnterAnim); } /** * 退出动画 */ private void exitAnimation(){ if(mExitAnim==null){ mExitAnim=new TranslateAnimation(1, 0, 1, 0, 1, 0, 1, 1); mExitAnim.setDuration(500); mExitAnim.setAnimationListener( new AnimationListener() { @Override public void onAnimationStart(Animation animation) { } @Override public void onAnimationRepeat(Animation animation) { } @Override public void onAnimationEnd(Animation animation) { dismissDialog(); //动画完成执行关闭 } }); } mCreateView.startAnimation(mExitAnim); } /** * 执行关闭 */ private void dismissDialog() { super.dismiss(); } /** * 执行动画 */ @Override public void dismiss() { exitAnimation(); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_MENU) { dismiss(); } return super.onKeyDown(keyCode, event); } } 自定义TextView控件：（优化drawable图片显示问题）
package cn.zszh.customs.view;import android.content.Context;import android.graphics.drawable.Drawable;import android.util.AttributeSet;public class TextView extends android.widget.TextView{private Context mContext;private int mWidth=30;private int mHeight=30;//保存设置的图片 private Drawable mLeft, mTop, mRight, mBottom;public TextView(Context context) {this(context,null);}public TextView(Context context, AttributeSet attrs) {super(context, attrs);mContext=context;init();}private void init() {float density=mContext.getResources().getDisplayMetrics().density;//将dip转化成pxmWidth*=density;mHeight*=density;//手动调用该方法，设置文字上下左右方向的图片宽高 setCompoundDrawablesWithIntrinsicBounds(mLeft, mTop, mRight, mBottom);//设置图片的宽高}/** * 重写该方法，文字上下左右方向的图片大小设置 * @param left * @param top * @param right * @param bottom */ @Override public void setCompoundDrawablesWithIntrinsicBounds( Drawable left, Drawable top, Drawable right, Drawable bottom) { if (left != null) { left.setBounds(0, 0, mWidth, mHeight); mLeft=left; } if (right != null) { right.setBounds(0, 0, mWidth, mHeight); mRight=right; } if (top != null) { top.setBounds(0, 0, mWidth, mHeight); mTop=top; } if (bottom != null) { bottom.setBounds(0, 0, mWidth, mHeight); mBottom=bottom; } setCompoundDrawables(left, top, right, bottom);//设置图片的宽高 } /** * 设置图片的宽高 * @param width * @param height */ public void setBounds(int width,int height){ mWidth=width; mHeight=height; init(); }}好了，将上面的代码复制到相应的位置就可以实现如上图的效果，具体分享功能需要自己动手做了（图中的几个分享图片资源需要自己找）。
