Android 轻松实现图片倒影效果实例代码

易采站长站为您分析Android 轻松实现图片倒影效果实例代码，有需要的朋友可以参考一下    

主Activity

复制代码
package com.mj.myweather;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.widget.ImageView;
import com.mj.myweather.utils.ImageUtil;

 

public class ImageActivity extends Activity {

// 声明控件
private ImageView mImageView01, mImageView02;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.image);
setupViews();

}
private void setupViews() {
mImageView01 = (ImageView) findViewById(R.id.image01);
mImageView02 = (ImageView) findViewById(R.id.image02);
// 获取壁纸返回值是Drawable
Drawable drawable = getWallpaper();
// 将Drawable转化为Bitmap
Bitmap bitmap = ImageUtil.drawableToBitmap(drawable);
// 缩放图片
Bitmap zoomBitmap = ImageUtil.zoomBitmap(bitmap, 300, 300);
// 获取圆角图片
Bitmap roundBitmap = ImageUtil
.getRoundedCornerBitmap(zoomBitmap, 10.0f);
// 获取倒影图片
Bitmap reflectBitmap = ImageUtil
.createReflectionImageWithOrigin(roundBitmap);
// 这里可以让Bitmap再转化为Drawable
// Drawable roundDrawable = new BitmapDrawable(roundBitmap);
// Drawable reflectDrawable = new BitmapDrawable(reflectBitmap);
// mImageView01.setBackgroundDrawable(roundDrawable);
// mImageView02.setBackgroundDrawable(reflectDrawable);
mImageView01.setImageBitmap(roundBitmap);
mImageView02.setImageBitmap(reflectBitmap);
}
}
