Я не могу решить эту ошибку, и я потратил больше часа, чтобы решить проблему, но не могу определить.Ошибка в текстовом виде
mainactivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.list_item);
mDrawerListItems = getResources().getStringArray(R.array.nav_drawer_labels);
mDrawerList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.activity_list_item, mDrawerListItems));
mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
int editedPosition = position + 1;
Toast.makeText(MainActivity.this, "You Selected item" + editedPosition, Toast.LENGTH_SHORT).show();
mDrawerLayout.closeDrawer(mDrawerList);
}
});
mDrawerToggle = new ActionBarDrawerToggle(this,
mDrawerLayout,
toolbar,
R.string.drawer_open,
R.string.drawer_close) {
public void onDrawerClosed(View v) {
super.onDrawerClosed(v);
invalidateOptionsMenu();
syncState();
}
public void onDrawerOpened(View v) {
super.onDrawerOpened(v);
invalidateOptionsMenu();
syncState();
}
};
/*drawerFragment = (FragmentDrawer)
getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
drawerFragment.setUp(R.id.fragment_navigation_drawer, (DrawerLayout) findViewById(R.id.drawer_layout), mToolbar);
drawerFragment.setDrawerListener(this);*/
}
И я получаю сообщение об ошибке в журнале

И я использую андроид инструмент Студия
Было бы полезно, если бы кто-то предложить мне, где я нахожусь неправильно.
Пожалуйста, вставьте полный лог. Здесь номер строки произошла ошибка в вашем журнале. Это поможет понять проблему. Но из-за ошибки ясно, что где-то вы используете линейную компоновку, и вы пытаетесь присвоить ее Textview. – Rekha
