原因：android.view.InflateException：二进制XML文件第9行：错误膨胀了类android.widget.ImageView

Question

我还没有找到答案。 我刚刚开始在android studio中学习编程，现在遇到了一些麻烦。 我无法解析代码中发生的事情。 我正在从几个月前最后一次编辑的在线教程中学习，视频中的那个家伙根本没有问题。 下面是代码截图。 提前致谢！！

MainActivity.java

public class MainActivity extends Activity implements View.OnClickListener{
    private ImageView mozartImage;
    private ImageView bachImage;

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

        mozartImage = (ImageView) findViewById(R.id.imageViewMozartId);
        bachImage = (ImageView) findViewById(R.id.imageViewBachId);

        mozartImage.setOnClickListener(this);
        bachImage.setOnClickListener(this);

    }

    @Override

    public void onClick(View v) {

        switch (v.getId()) {

            case R.id.imageViewMozartId:

                Intent mozartIntent = new Intent(MainActivity.this, DetailsActivity.class);
                String mozartBio = "Wolfgang Amadeus Mozart was born in Salzburg and showed prodigious ability" +
                        "from his earliest childhood. Already competent on keyboard and violin, he composed from the age of five " +
                        "and performed before European royalty. At 17. he was engaged as a court musician in Salzburg. ";
                mozartIntent.putExtra("mozart", mozartBio);
                mozartIntent.putExtra("name", "Wolfgang Amadeus Mozart");
                startActivity(mozartIntent);

                break;
            case R.id.imageViewBachId:

                Intent bachIntent = new Intent(MainActivity.this, DetailsActivity.class);
                String bachBio = "Johann Sebastian Bach was born in Eisenach, Saxe-Eisenach, into a great musical family. " +
                        "His father, Johann Ambrosius Bach, was the director of the town musicians, " +
                        "and all of his uncles were proffesional musicians. His father taught him to play the violin. ";
                bachIntent.putExtra("bach", bachBio);
                bachIntent.putExtra("name", "Johann Sebastian Bach");
                startActivity(bachIntent);
                break;

        }

    }
}

DetailsActivity

public class DetailsActivity extends Activity {

    private ImageView profileImage;
    private TextView bioText;
    private Bundle extras;

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

        profileImage = (ImageView) findViewById(R.id.imageViewBioId);
        bioText = (TextView) findViewById(R.id.textViewBioId);

        extras = getIntent().getExtras();

        if (extras != null) {

            String name = extras.getString("name");
            showDetails(name);

        }
    }


    public void showDetails(String nName) {

        Toast.makeText(this, nName, Toast.LENGTH_LONG).show();
        if (nName.equals("mozart")) {

            profileImage.setImageDrawable(ContextCompat.getDrawable(this, R.drawable.mozart));
            bioText.setText(extras.getString("nName"));

        } else if (nName.equals("bach")) {
            profileImage.setImageDrawable(ContextCompat.getDrawable(this, R.drawable.bach));
            bioText.setText(extras.getString("nName"));
        }

    }
}

Answer 1

也许您ImageView与id imageViewMozartId它太大（101654796 = 96,95 mebibyte）。

您应使用大小和重量合理的jpeg或png图像。

Answer 2

关于图像/位图的某些信息会导致OutofMemory错误。 android开发人员页面建议使用文档中定义的这两种方法。 仔细阅读它一次对我的帮助很大。
