安卓界面-缓冲界面的用法

bufferInterface类：java代码示例

/*
 * 这是一个缓冲界面类
 * init()函数用来初始化界面;
 * initImage()函数用来初始化Imageview数组;
 * playAniamtion()函数用来创建一个进程，循环打印;
 * cleanImage()函数用来消除Imageview数组里面的内容;

public class bufferInterface {
    private static  Animation anm;           //首先先定义一个动画对象
    public static  int marginsTop;           

    public bufferInterface() {
        // TODO Auto-generated constructor stub
    }

        int height=dm.heightPixels;
        bufferInterface.marginsTop=height-;
        Log.i("marginsTop2", String.valueOf(marginsTop));
        anm=AnimationUtils.loadAnimation(context,R.anim.myanim);
        //加载动画的类型

    }

    public static void playAniamtion(final Handler handler)
    {
        new Thread()
        {
            @Override
            public void run() {
                // TODO Auto-generated method stub

                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                int runcount=;
                for(int a=;a<=;a++)
                {
                    if(runcount<)

                            }
                        }
                        runcount++;
                    }else
                    {
                        handler.sendEmptyMessage();
                        runcount=;
                    }
                }
            }
        }.start();
    }

    public static void initImage(Context context,LinearLayout layout,List<ImageView> images)
    {
        layout.setGravity(Gravity.CENTER_HORIZONTAL);//设置Linearlayout的居中类型

        LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(, );
        //设置单个imageview的布局大小
        param.setMargins(, marginsTop, , );
        //设置单个imageview在父视图上的位置

        LinearLayout.LayoutParams param2 = new LinearLayout.LayoutParams(, );
        param2.setMargins(-,marginsTop, , );

        ImageView l = new ImageView(context);
        l.setLayoutParams(param);
        layout.addView(l);
        images.add(l);

        ImageView o = new ImageView(context);
        o.setLayoutParams(param2);
        layout.addView(o);
        images.add(o);


        ImageView a = new ImageView(context);
        a.setLayoutParams(param2);
        layout.addView(a);
        images.add(a);

        ImageView d = new ImageView(context);
        d.setLayoutParams(param2);
        layout.addView(d);
        images.add(d);

        ImageView i = new ImageView(context);
        i.setLayoutParams(param2);
        layout.addView(i);
        images.add(i);

    }

     public static void clearImage(List<ImageView> images)
        {
            for(ImageView image:images)
            {
                image.setImageDrawable(null);     
                image.destroyDrawingCache();     //销毁imageview中的缓存
            }
        }
}
           

上面是我个人在前辈的基础上，写的一个bufferInterface类，意思就是缓冲界面啦

R.anim.myanim.xml代码，此代码用来设置动画播放的方式

<?xml version="1.0" encoding="utf-8"?>
<set 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
    <scale android:interpolator="@android:anim/accelerate_interpolator"
        android:fromXScale="0.5"    //开始x轴的相对于原图的倍数关系
        android:toXScale="1.2"      //结束x轴的相对于原图的倍数关系
        android:fromYScale="0.5"
        android:toYScale="1.2" 
        android:pivotX="50%"        
        android:pivotY="50%"
        android:fillAfter="false" 
        android:startOffset="-50"
        android:duration="100"
/>
</set>
           

主函数调用的java代码

public class mainActivity extends Activity {
    public LinearLayout layout;
    private Animation anm;
    public List<ImageView> images;
    public Handler handler=new Handler()
    {
        public void handleMessage(android.os.Message msg) {
            switch(msg.what)
            {
            case :
                images.get().setImageDrawable(mainActivity.this.getResources().getDrawable(R.drawable.l));
                images.get().startAnimation(anm);

                break;
            case :
                images.get().setImageDrawable(mainActivity.this.getResources().getDrawable(R.drawable.o));
                images.get().startAnimation(anm);
                break;
            case :
                images.get().setImageDrawable(mainActivity.this.getResources().getDrawable(R.drawable.a));
                images.get().startAnimation(anm);
                break;
            case :
                images.get().setImageDrawable(mainActivity.this.getResources().getDrawable(R.drawable.d));
                images.get().startAnimation(anm);
                break;
            case :
                images.get().setImageDrawable(mainActivity.this.getResources().getDrawable(R.drawable.i));
                images.get().startAnimation(anm);
                break;
            case :
                images.get().setImageDrawable(mainActivity.this.getResources().getDrawable(R.drawable.n));
                images.get().setAnimation(anm);
                break;
            case :
                images.get().setImageDrawable(mainActivity.this.getResources().getDrawable(R.drawable.g));
                images.get().setAnimation(anm);
                break;
            case :
                Intent intent=new Intent(mainActivity.this, secondActivity.class);
                startActivity(intent);
                break;
            }   
        };
    };
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN );
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        layout=new LinearLayout(this);
        images=new ArrayList<ImageView>();
        anm=UI.bufferInterface.init(this, layout);
        UI.bufferInterface.initImage(this, layout, images);
        UI.bufferInterface.playAniamtion(handler);
        setContentView(layout); 
    }
}
