抽屉导航栏的 DrawerArrowToggle 动画

Question

我想使用 Google 的动画在打开导航栏时将导航图标变为箭头，然后将其变为抽屉式导航图标。我还想知道在移动到另一个活动时是否可以保持操作栏静止。

这个问题已经过时并且不再相关，因为 Material Design 中的导航抽屉已经在一个简单而无缝的过程中为开发人员提供，不再需要开发人员将汉堡侧菜单添加到后退箭头动画中，因为它已经是提供。

     menutitles = getResources().getStringArray(R.array.sidebar);
            mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
            mDrawerList = (ListView) findViewById(R.id.slider_list);

            mDrawerList.setAdapter(new ArrayAdapter<String>(this,
                    R.layout.list_tem, R.id.title, menutitles));
            // Set the list's click listener
            mTitle = mDrawerTitle = getTitle();
            mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
            mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
                    R.mipmap.drawer, R.string.drawer_open, R.string.drawer_close) {

                /**
                 * Called when a drawer has settled in a completely closed state.
                 */
                public void onDrawerClosed(View view) {
                    super.onDrawerClosed(view);
                    getActionBar().setTitle(mTitle);
                    invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
                }

                /**
                 * Called when a drawer has settled in a completely open state.

                    invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
                }
            };

            // Set the drawer toggle as the DrawerListener
            mDrawerLayout.setDrawerListener(mDrawerToggle);
            getActionBar().setDisplayHomeAsUpEnabled(true);
            getActionBar().setHomeButtonEnabled(true);

    /**   * When using the ActionBarDrawerToggle, you must call it during   * onPostCreate() and onConfigurationChanged()...   */
    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        // Sync the toggle state after onRestoreInstanceState has occurred.
        mDrawerToggle.syncState();    }
    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        // Pass any configuration change to the drawer toggles
        mDrawerToggle.onConfigurationChanged(newConfig);
    }
    /** Swaps fragments in the main content view */
    private void selectItem(int position) {

        // Create a new fragment and specify the planet to show based on position


        // Highlight the selected item, update the title, and close the drawer
        mDrawerList.setItemChecked(position, true);

    }

    @Override
    public void setTitle(CharSequence title) {
        mTitle = title;
        getActionBar().setTitle(mTitle);
    }




    private class DrawerItemClickListener implements ListView.OnItemClickListener {
        @Override
        public void onItemClick(AdapterView parent, View view, int position, long id) {
            selectItem(position);
        }
    }

}

我想使用谷歌的动画在打开导航栏时将导航图标变为箭头，然后将其变回抽屉导航图标

查看构造函数调用，很明显您使用的是ActionBarDrawerToggle 的v4 支持版本。如果你想要汉堡箭头动画，你需要使用 v7 appcompat 版本。

为此，首先将 v7 appcompat 库添加到您的项目中。然后，在ActionBarDrawerToggleimport 语句中，将v4 更改为v7，并在构造函数调用中删除R.mipmap.drawer 参数。

import android.support.v7.app.ActionBarDrawerToggle;
...

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
    R.string.drawer_open, R.string.drawer_close) {...}

我也想知道在移动到另一个活动时是否可以保持操作栏静止。

如果你想使用导航抽屉模式，你应该为不同的部分使用Fragments，而不是为每个部分打开一个新的Activity。鉴于代码中的 cmets，您所遵循的示例演示了如何执行此操作。
