篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了android项目智慧北京开发完整步骤：第一天相关的知识，希望对你有一定的参考价值。
去掉标题，全屏
动画
rlRoot= (RelativeLayout)findViewById(R.id.rl_root);
RotateAnimation animRotate=newRotateAnimation(0, 360, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
animRotate.setDuration(1000);
animRotate.setFillAfter(true);//保持状体
ScaleAnimation animScale=newScaleAnimation(0, 1, 0, 1, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
animScale.setDuration(1000);
animScale.setFillAfter(true);
AlphaAnimation animAlpha=newAlphaAnimation(0, 1);
animAlpha.setDuration(1000);
animAlpha.setFillAfter(true);
AnimationSet animSet=newAnimationSet(true);
animSet.addAnimation(animRotate);
animSet.addAnimation(animAlpha);
animSet.addAnimation(animScale);
rlRoot.startAnimation(animSet);
animSet.setAnimationListener(newAnimationListener() {
@Override
publicvoidonAnimationStart(Animation animation) {
}
@Override
publicvoidonAnimationRepeat(Animation animation) {
}
@Override
publicvoidonAnimationEnd(Animation animation) {
startActivity(newIntent(getApplicationContext(), MainActivity.class));
finish();
}
});
库文件
打包不需要管库文件，自动打到项目里
引导页（ViewPage）
xml文件
拷贝全路径
关联viewPage源码
先remove
Addjar
勾上
源码路径
E:\adt-bundle-windows-x86\sdk\extras\android\support\v4
java代码
privateint[]mImageIds=newint[]{R.drawable.guide_1,R.drawable.guide_2,R.drawable.guide_3};
privateViewPagermViewPage;
privateArrayListmImageViewList;
@Override
protectedvoidonCreate(Bundle savedInstanceState) {
//TODOAuto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_guide);
mViewPage= (ViewPager) findViewById(R.id.vp_pager);
mViewPage.setAdapter(newMyAdapter());
mImageViewList=newArrayList();
for(inti = 0; i
ImageView view=newImageView(this);
view.setBackgroundResource(mImageIds[i]);
mImageViewList.add(view);
}
}
classMyAdapterextendsPagerAdapter{
@Override
publicintgetCount() {
returnmImageIds.length;
}
@Override
publicbooleanisViewFromObject(View view, Object object) {
returnview==object;
}
@Override
publicObject instantiateItem(ViewGroup container,intposition) {
//ImageView view=new ImageView(getApplicationContext());
//view.setBackgroundResource(mImageIds[position]);
ImageView view=mImageViewList.get(position);
container.addView(view);
returnview;
}
@Override
publicvoiddestroyItem(ViewGroup container,intposition, Object object) {
container.removeView((View)object);
}
}
加点，加按钮
java代码

pointView.setImageResource(R.drawable.shape_circle_default);
LinearLayout.LayoutParams params=newLinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);
if(i>0){
params.leftMargin=10;//从第二个点开始设置边距
}
pointView.setLayoutParams(params);
llContainer.addView(pointView);
}
mViewPage.setAdapter(newMyAdapter());
//页面绘制结束后，计算两个圆点的距离
ivRedPoint.getViewTreeObserver().addOnGlobalLayoutListener(newOnGlobalLayoutListener() {
//layout方法执行结束之后(位置确定)
@Override
publicvoidonGlobalLayout() {
//移除监听
ivRedPoint.getViewTreeObserver().removeGlobalOnLayoutListener(this);

}
});
//页面滑动过程中回调

}else

}

intleftMargin=(int)(mPointWith*positionOffset+position*mPointWith);
//修改小红点的左边距
RelativeLayout.LayoutParams params=(LayoutParams)ivRedPoint.getLayoutParams();
params.leftMargin=leftMargin;
ivRedPoint.setLayoutParams(params);
}
@Override
