Question

我不知道这是什么错误。之前工作正常，但它突然破裂了;我不知道为什么。在我更改我的图标之前，我已经将其更改回来但仍然出错。请帮忙。如果它是关于我认为没有的图像，因为我在登录活动中使用图像但它很好

这是我的java

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

            new daftarMahasiswa().execute();
        }
 public void pinjamKelas(){
        LinearLayout pinjamkelas = (LinearLayout) findViewById(R.id.pinjam_kelas);
        pinjamkelas.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(MainActivity.this, KelasActivity.class);

    public static void setListViewHeightBasedOnChildren(ListView listView) {
        ListAdapter listAdapter = listView.getAdapter();
        if (listAdapter == null) return;
        int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(), View.MeasureSpec.UNSPECIFIED);

Answer 1

只需清理您的项目并尝试重建它。

Answer 2

试试这个：

android.enableAapt2=false

它可以帮助你

Answer 3

您是否将此res / xml / preference_headers.xml添加到资源目录中？
将android.enableAapt2 = false添加到gradle.properties文件中

无法启动活动ComponentInfo android.content.res.Resources $ NotFoundException：资源ID
