android studio图片轮播布局代码

以下是一个Android Studio图片轮播布局的代码示例：

import android.content.Context;
import android.os.Handler;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.FrameLayout;
import android.widget.ImageView;
import android.widget.LinearLayout;

import java.util.ArrayList;
import java.util.List;

public class ImageSlider extends FrameLayout {

    private Context mContext;
    private ViewPager mViewPager;
    private LinearLayout mIndicatorLayout;
    private List<ImageView> mIndicatorViews;
    private List<Integer> mImageList;
    private int mCurrentPosition = 0;
    private Handler mHandler;
    private Runnable mRunnable;

    public ImageSlider(Context context) {
        this(context, null);
    }

    public ImageSlider(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public ImageSlider(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        mContext = context;
        LayoutInflater.from(context).inflate(R.layout.image_slider_layout, this);
        mViewPager = findViewById(R.id.viewPager);
        mIndicatorLayout = findViewById(R.id.indicatorLayout);
        mImageList = new ArrayList<>();
        mIndicatorViews = new ArrayList<>();
        mHandler = new Handler();
        mRunnable = new Runnable() {
            @Override
            public void run() {
                mCurrentPosition++;
                if (mCurrentPosition >= mImageList.size()) {
                    mCurrentPosition = 0;
                }
                mViewPager.setCurrentItem(mCurrentPosition);
                mHandler.postDelayed(this, 3000);
            }
        };
    }

    public void setImageList(List<Integer> imageList) {
        mImageList.clear();
        mImageList.addAll(imageList);
        initViewPager();
        initIndicator();
        startAutoPlay();
    }

    private void initViewPager() {
        ImageSliderAdapter adapter = new ImageSliderAdapter(mContext, mImageList);
        mViewPager.setAdapter(adapter);
        mViewPager.setCurrentItem(mCurrentPosition);
    }

    private void initIndicator() {
        mIndicatorLayout.removeAllViews();
        mIndicatorViews.clear();
        for (int i = 0; i < mImageList.size(); i++) {
            ImageView indicatorView = new ImageView(mContext);
            LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
                    LinearLayout.LayoutParams.WRAP_CONTENT,
                    LinearLayout.LayoutParams.WRAP_CONTENT
            );
            params.setMargins(10, 0, 10, 0);
            indicatorView.setLayoutParams(params);
            if (i == mCurrentPosition) {
                indicatorView.setImageResource(R.drawable.indicator_selected);
            } else {
                indicatorView.setImageResource(R.drawable.indicator_unselected);
            }
            mIndicatorViews.add(indicatorView);
            mIndicatorLayout.addView(indicatorView);
        }
    }

    private void startAutoPlay() {
        mHandler.postDelayed(mRunnable, 3000);
    }

    private void stopAutoPlay() {
        mHandler.removeCallbacks(mRunnable);
    }

    @Override
    protected void onDetachedFromWindow() {
        super.onDetachedFromWindow();
        stopAutoPlay();
    }
}

请注意，上述代码是一个自定义的图片轮播布局，需要在布局文件中引用。同时，还需要创建一个适配器类`ImageSliderAdapter`来设置ViewPager的内容。
