本篇文章为大家展示了怎么在Android中利用Glide获取图片的宽高,内容简明扼要并且容易理解,绝对能使你眼前一亮,通过这篇文章的详细介绍希望你能有所收获。
//获取图片显示在ImageView后的宽高 Glide.with(this) .load(imgUrl) .asBitmap()//强制Glide返回一个Bitmap对象 .listener(new RequestListener<String, Bitmap>() { @Override public boolean onException(Exception e, String model, Target<Bitmap> target, boolean isFirstResource) { Log.d(TAG, "onException " + e.toString()); return false; } @Override public boolean onResourceReady(Bitmap bitmap, String model, Target<Bitmap> target, boolean isFromMemoryCache, boolean isFirstResource) { int width = bitmap.getWidth(); int height = bitmap.getHeight(); Log.d(TAG, "width3 " + width); //400px Log.d(TAG, "height2 " + height); //400px return false; } }).into(mIv_img);
想要拿到图片真正的宽高,应该利用Glide的Target。如下:
//获取图片真正的宽高 Glide.with(this) .load(imgUrl) .asBitmap()//强制Glide返回一个Bitmap对象 .into(new SimpleTarget<Bitmap>() { @Override public void onResourceReady(Bitmap bitmap, GlideAnimation<? super Bitmap> glideAnimation) { int width = bitmap.getWidth(); int height = bitmap.getHeight(); Log.d(TAG, "width " + width); //200px Log.d(TAG, "height " + height); //200px } });

public class MainActivity extends AppCompatActivity { private ImageView mIv_img; String imgUrl = "https://file.lsjlt.com/upload/202305/30/fi4m0ppwoej.jpg"; private String TAG = this.getClass().getSimpleName(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mIv_img = (ImageView) findViewById(R.id.iv_img); //获取图片真正的宽高 Glide.with(this) .load(imgUrl) .asBitmap()//强制Glide返回一个Bitmap对象 .into(new SimpleTarget<Bitmap>() { @Override public void onResourceReady(Bitmap bitmap, GlideAnimation<? super Bitmap> glideAnimation) { int width = bitmap.getWidth(); int height = bitmap.getHeight(); Log.d(TAG, "width " + width); //200px Log.d(TAG, "height " + height); //200px } }); //获取图片显示在ImageView后的宽高 Glide.with(this) .load(imgUrl) .asBitmap()//强制Glide返回一个Bitmap对象 .listener(new RequestListener<String, Bitmap>() { @Override public boolean onException(Exception e, String model, Target<Bitmap> target, boolean isFirstResource) { Log.d(TAG, "onException " + e.toString()); return false; } @Override public boolean onResourceReady(Bitmap bitmap, String model, Target<Bitmap> target, boolean isFromMemoryCache, boolean isFirstResource) { int width = bitmap.getWidth(); int height = bitmap.getHeight(); Log.d(TAG, "width3 " + width); //400px Log.d(TAG, "height2 " + height); //400px return false; } }).into(mIv_img); }}
