以编程方式减小ImageView的大小(使用java代码)

import android.app.Activity;
import android.os.Bundle;
import android.view.ViewGroup;
import android.widget.ImageView;

public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ImageView imageView = findViewById(R.id.image_view);
        ViewGroup.LayoutParams layoutParams = imageView.getLayoutParams();
        layoutParams.width = 100; // 设置ImageView的宽度为100像素
        layoutParams.height = 100; // 设置ImageView的高度为100像素
        imageView.setLayoutParams(layoutParams);
    }
}
