Android将html文件从本地文件夹加载到webview中

Question

任务：我已经创建了一个片段抽屉，在这里我有textview，文本“MyName”就在我的图像下面，然后有nav_row项，所以我想做的是，当单击该文本时，它应该将活动从MainActivity切换到profileinfo，我创建了webview，它的活动profileinfo应该加载我的html文件...所以我做的是这里-->

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <LinearLayout
            android:id="@+id/container_toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <include
                android:id="@+id/toolbar"
                layout="@layout/toolbar" />
        </LinearLayout>

        <FrameLayout
            android:id="@+id/container_body"
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_weight="1" />

        <webview xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/aboutYou"
            android:orientation="vertical" android:layout_width="match_parent"
            android:layout_height="match_parent">
        </webview>
    </LinearLayout>


    <fragment
        android:id="@+id/fragment_navigation_drawer"
        android:name="com.medmainfomatix.mdesign.FragmentDrawer"
        android:layout_width="@dimen/nav_drawer_width"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:layout="@layout/fragment_navigation_drawer"
        tools:layout="@layout/fragment_navigation_drawer" />

</android.support.v4.widget.DrawerLayout>

webview xml在这里-->

<?xml version="1.0" encoding="utf-8"?>
<webview xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/aboutYou"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">
</webview>

profileinfo活动

public class profileinfo extends AppCompatActivity{
    private WebView aboutYou;


    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webview);
        aboutYou = (WebView) findViewById(R.id.aboutYou);
        aboutYou.loadUrl("file:///android_assets/profile_info.html");
    }
}

这是我的主要活动课

private static String TAG = MainActivity.class.getSimpleName();
TextView pname;
private Toolbar mToolbar;

private FragmentDrawer drawerFragment;

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

    mToolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(mToolbar);
    getSupportActionBar().setDisplayShowHomeEnabled(true);
    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);

    displayView(0);
    pname = (TextView) findViewById(R.id.pname);


    pname.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent inent = new Intent(MainActivity.this,profileinfo.class);

            startActivity(inent);
        }
    });
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        Toast.makeText(getApplicationContext(), "Search action is selected!", Toast.LENGTH_SHORT).show();
        return true;
    }

    return super.onOptionsItemSelected(item);
}

@Override
public void onDrawerItemSelected(View view, int position) {
    displayView(position);
}
private void displayView(int position) {
    Fragment fragment = null;
    String title = getString(R.string.app_name);
    switch (position) {
        case 0:
            fragment = new HomeFragment();
            title = getString(R.string.title_home);
            break;
        case 1:
            fragment = new FriendsFragment();
            title = getString(R.string.title_friends);
            break;
        case 2:
            fragment = new MessagesFragment();
            title = getString(R.string.title_messages);
            break;
        default:
            break;
    }

    if (fragment != null) {
        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.container_body, fragment);
        fragmentTransaction.commit();

        // set the toolbar title
        getSupportActionBar().setTitle(title);
    }
}

不要担心其他类和xml，请看一下我错在哪里。

试试这个
它对我有用

WebView webView = (WebView)findViewById(R.id.webView1);
webview.loadUrl("file:///android_asset/file.html");
