Question

我编写了这段代码，但我不知道我遇到了什么问题以及如何解决它。我想显示800个标题的列表，我想从要显示5秒钟的imageView开始，然后我要转到主页。当我尝试运行时，出现此错误：图像太大。我已经将图像转换为webp，现在的重量为1.9Mb。我不知道为什么图像太大？

public class activity_intro extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_intro);

        ImageView img_intro = (ImageView) findViewById(R.id.img_intro); // Create an icon
        Picasso.get().load(R.drawable.img_intro).into(img_intro);

        new CountDownTimer(5000, 1000) {

            public void onTick(long millisUntilFinished) {

            }

            public void onFinish() {
                final Intent intro_toMain = new Intent(activity_intro.this, Activity_Main.class);
                startActivity(intro_toMain);
            }
        }.start();
    }

}

这是LogCat

Answer 1

它表示图像尺寸太大。因此，使用-

Picasso.get().load(R.drawable.img_intro).resize(100, 200).centerCrop().into(img_intro);

其中100表示宽度，200表示高度。

android图片太大而无法绘制
