Question

我希望导航抽屉显示单击按钮，因此我使用以下代码。我在自定义适配器中处理单击事件，但是当单击列表中的任何对象时，抽屉不会在任何时间点关闭。知道怎么解决这个问题吗？另一个问题是我只能从屏幕的底部到中间绘制导航抽屉。我该如何解决这个问题？在我的活动中

mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerList = (ListView) findViewById(android.R.id.list);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            if (mDrawerLayout.isDrawerOpen(Gravity.RIGHT)) {
                mDrawerLayout.closeDrawer(Gravity.RIGHT);
            } else {
                mDrawerLayout.openDrawer(Gravity.RIGHT);
            }
        }
    });


    String[] values = new String[] { "1:","2","","3"};
    MySimpleArrayAdapterUhr adapter = new MySimpleArrayAdapterUhr(this, values);
    setListAdapter(adapter);
    mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                                int position, long id) {

            // Closing the drawer
            mDrawerLayout.closeDrawers();

        }
    });

我的适配器：

public class MySimpleArrayAdapter extends ArrayAdapter<String> {

private final Activity context;
private final String[] names;

static class ViewHolder {
    public TextView text;
    public ImageView image;
    public LinearLayout full;
}

public MySimpleArrayAdapter(Activity context, String[] names) {
    super(context, R.layout.drawer_list_item, names);
    this.context = context;
    this.names = names;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View rowView = convertView;
    // reuse views
    if (rowView == null) {
        LayoutInflater inflater = context.getLayoutInflater();
        rowView = inflater.inflate(R.layout.drawer_list_item, null);
        // configure view holder
        ViewHolder viewHolder = new ViewHolder();
        viewHolder.full = (LinearLayout) rowView.findViewById(R.id.full);
        viewHolder.text = (Button) rowView.findViewById(R.id.label);
        viewHolder.image = (ImageView) rowView.findViewById(R.id.image);

        rowView.setTag(viewHolder);
    }

    // fill data
    ViewHolder holder = (ViewHolder) rowView.getTag();
    String s = names[position];
    holder.text.setText(s);
    if (s.equals("1")) {
        holder.text.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                switch (event.getAction()) {
                    case MotionEvent.ACTION_DOWN: {
                        v.invalidate();
                        break;
                    }
                    case MotionEvent.ACTION_UP:
                        v.playSoundEffect(android.view.SoundEffectConstants.CLICK);
                        Intent intent = new Intent(context, activity_einstellungen_ereignis_erstellen.class);
                        v.getContext().startActivity(intent);
                    case MotionEvent.ACTION_CANCEL: {
                        Button view = (Button) v;
                        view.invalidate();
                        break;
                    }
                }
                return true;
        });
    }
    return rowView;
}

}

try this code
declare variable as   private ActionBarDrawerToggle mDrawerToggle;
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 
    mDrawerList = (ListView) findViewById(android.R.id.list); 
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            if (mDrawerLayout.isDrawerOpen(Gravity.RIGHT)) {
                mDrawerLayout.closeDrawer(Gravity.RIGHT);
            } else { 
                mDrawerLayout.openDrawer(Gravity.RIGHT);
            } 
        } 
    }); 


    String[] values = new String[] { "1:","2","","3"}; 
    MySimpleArrayAdapterUhr adapter = new MySimpleArrayAdapterUhr(this, values); 
    setListAdapter(adapter); 

// enabling action bar app icon and behaving it as toggle button
        getActionBar().setDisplayHomeAsUpEnabled(true);
        getActionBar().setHomeButtonEnabled(true);

        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
                R.drawable.ic_drawer, //nav menu toggle icon
                R.string.app_name, // nav drawer open - description for accessibility
                R.string.app_name // nav drawer close - description for accessibility
        ){
            public void onDrawerClosed(View view) {
                getActionBar().setTitle(mTitle);
                // calling onPrepareOptionsMenu() to show action bar icons
                invalidateOptionsMenu();
            }

            public void onDrawerOpened(View drawerView) {
                getActionBar().setTitle(mDrawerTitle);
                // calling onPrepareOptionsMenu() to hide action bar icons
                invalidateOptionsMenu();
            }
        };

if (savedInstanceState == null) {
            // on first time display view for first nav item
            displayView(0);
        } <br>
