java - 使用 ScrimInsetFrameLayout 出错

Question

我正在使用 ScrimInsetsFrameLayout在 ToolBar 上获取 Navigation Drawer 并在其上设置 StatusBar 所以我按照指南阅读了很多关于它的内容，但甚至出现了一些问题如果我没有遗漏任何东西。

每当我单击 drawer_listView 或 ic_drawer 中的(四个) Activity 之一时，应用程序强制关闭，Logcat 中没有消息。

主 Activity

public class MainActivity extends ActionBarActivity {

DrawerLayout mDrawerLayout;
ListView mDrawerList;
ActionBarDrawerToggle mDrawerToggle;
String[] mDrawerListItems;

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

    Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);

    mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer);
    mDrawerLayout.setStatusBarBackgroundColor(getResources().getColor(R.color.primaryDark));
    mDrawerList = (ListView)findViewById(android.R.id.list);
    mDrawerListItems = getResources().getStringArray(R.array.drawer_list);
    mDrawerList.setAdapter(new ArrayAdapter<>
            (this, android.R.layout.simple_list_item_1, mDrawerListItems));
    mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            openFragment(position);
        }
    });
    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();
        }
    };
    mDrawerLayout.setDrawerListener(mDrawerToggle);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);
    mDrawerToggle.syncState();
}

protected void openFragment(int position){

    mDrawerLayout.closeDrawer(mDrawerList);

    switch (position) {
        case 0:
            startActivity(new Intent(this, WIND.class));
            break;
        case 1:
            startActivity(new Intent(this, GEO.class));
            break;
        case 2:
            startActivity(new Intent(this, COMPASS.class));
            break;
        case 3:
            startActivity(new Intent(this, BARO_ALTI.class));
            break;
        default:
            break;
    }

}

@Override
protected void onPostCreate(Bundle savedInstanceState){
    super.onPostCreate(savedInstanceState);
    mDrawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig){
    super.onConfigurationChanged(newConfig);
    mDrawerToggle.onConfigurationChanged(newConfig);
}

@Override
public boolean onOptionsItemSelected(MenuItem item){
    switch (item.getItemId()){
        case android.R.id.home: {
            if (mDrawerLayout.isDrawerOpen(mDrawerList)){
                mDrawerLayout.closeDrawer(mDrawerList);
            } else {
                mDrawerLayout.openDrawer(mDrawerList);
            }
            return true;
        }
        default: return super.onOptionsItemSelected(item);
    }
}

my_activity.xml:

<?xml version="1.0"?>
<android.support.v4.widget.DrawerLayout
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:android="http://schemas.android.com/apk/res/android"

        android:layout_gravity="start"
        android:scrollbars="none"/>

</beta_toolbox.pier.beta_toolbox.ScrimInsetsFrameLayout>

我的问题仅限于 my_activity.xml。请帮助我，我无法继续我的项目。

[更新]

我的布局和他做的一模一样https://github.com/google/iosched/blob/master/android/src/main/res/layout/activity_map.xml但是**为什么我没有得到相同的结果？!**

Answer 1

只需将 setSupportActionBar(toolbar); 放在 Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar); 下

现在您应该可以单击 ic_drawer 以打开 drawer_layout。

(您将无法点击该列表的 Activity ，我会尝试解决该问题。明天我会更新我的答案)

编辑:

public class MainActivity extends ActionBarActivity {

DrawerLayout mDrawerLayout;
ListView mDrawerList;
ActionBarDrawerToggle mDrawerToggle;
String[] mDrawerListItems;

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

    Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);

    mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer);
    mDrawerLayout.setStatusBarBackgroundColor(getResources().getColor(R.color.primaryDark));

    mDrawerListItems = getResources().getStringArray(R.array.drawer_list);

    mDrawerList = (ListView)findViewById(android.R.id.list);
    mDrawerList.setAdapter(new ArrayAdapter<>
            (this, android.R.layout.simple_list_item_1, mDrawerListItems));
    mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            openFragment(position);
        }

    mDrawerToggle = new ActionBarDrawerToggle(this,

        default:
