我是一個帶抽屜的初學者。 我採取了可用的星球上的例子https://developer.android.com/training/implementing-navigation/nav-drawer.html我的抽屜有兩個問題：1.抽屜不滾動2.抽屜沒有通過滑動關閉
我開始更新它爲我的應用程序。
我的問題是，listview不滾動。我認爲這是默認的列表視圖滾動，你不必通過scrollview環繞。也許我有我的佈局問題：
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.
The drawer is given a fixed width in dp and extends the full height of
the container. A solid background is used for contrast
with the content view. -->
<ListView
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button
android:id="@+id/db"
android:text="Databse"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<ListView
android:id="@+id/listViewPeople"
android:layout_height="120dp"
android:layout_below="@id/db"
android:layout_width="match_parent"/>
<Button
android:id="@+id/disc"
android:text="Discovery"
android:layout_marginTop="10dp"
android:layout_below="@id/listViewPeople"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/state"
android:text="state"
android:layout_below="@id/disc"
android:layout_height="30dp"
android:layout_width="match_parent"/>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="@id/state"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:id="@+id/emails"
android:layout_marginTop="20dp"
android:text="12345"
android:layout_height="match_parent"
android:layout_width="match_parent"/>
</ScrollView>
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
而且我的strings.xml樣子：
<resources>
<string name="app_name">CheckSecurity</string>
<string name="yes">Yes</string>
<string name="no">No</string>
<string name="action_settings">Settings</string>
<string-array name="planets_array">
<item>Mercury</item>
<item>Venus</item>
<item>Earth</item>
<item>Mars</item>
<item>Jupiter</item>
<item>Saturn</item>
<item>Uranus</item>
<item>Neptune</item>
<item>1</item>
<item>2</item>
<item>3</item>
<item>4</item>
<item>5</item>
<item>6</item>
<item>7</item>
<item>8</item>
<item>9</item>
<item>10</item>
</string-array>
<string name="drawer_open">Open navigation drawer</string>
<string name="drawer_close">Close navigation drawer</string>
<string name="action_websearch">Web search</string>
<string name="app_not_available">Sorry, there\'s no web browser available</string>
</resources>
我第二個問題是抽屜只能由巴反按鈕關閉。如果我向後滑動抽屜，它不會關閉。如果我選擇抽屜正常關閉的項目。不是簡單的滑動。我不能在代碼中管理它？
我用android.support.v7：
import android.os.Build;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
這裏是我的代碼：
private void initiateDrawer() {
mTitle = mDrawerTitle = getTitle();
mPlanetTitles = getResources().getStringArray(array.planets_array);
mDrawerLayout = (DrawerLayout) findViewById(id.drawer_layout);
mDrawerList = (ListView) findViewById(id.left_drawer);
// set a custom shadow that overlays the main content when the drawer opens
// mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
// set up the drawer's list view with items and click listener
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
layout.drawer_list_item, mPlanetTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
// enable ActionBar app icon to behave as action to toggle nav drawer
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the sliding drawer and the action bar app icon
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.string.drawer_open, /* "open drawer" description for accessibility */
R.string.drawer_close /* "close drawer" description for accessibility */
) {
public void onDrawerClosed(View view) {
getSupportActionBar().setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
getSupportActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerLayout.addDrawerListener(mDrawerToggle);
// if (savedInstanceState == null) {
// selectItem(0);
// }
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}
/* Called whenever we call invalidateOptionsMenu() */
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
// If the nav drawer is open, hide action items related to the content view
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(id.action_websearch).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// The action bar home/up action should open or close the drawer.
// ActionBarDrawerToggle will take care of this.
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
// Handle action buttons
switch(item.getItemId()) {
case id.action_websearch:
// create intent to perform web search for this planet
Intent intent = new Intent(Intent.ACTION_WEB_SEARCH);
intent.putExtra(SearchManager.QUERY, getSupportActionBar().getTitle());
// catch event that there's no activity to handle intent
if (intent.resolveActivity(getPackageManager()) != null) {
startActivity(intent);
} else {
Toast.makeText(this, string.app_not_available, Toast.LENGTH_LONG).show();
}
return true;
default:
return super.onOptionsItemSelected(item);
}
}
/* The click listner for ListView in the navigation drawer */
private class DrawerItemClickListener implements ListView.OnItemClickListener {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
}
private void selectItem(int position) {
// update the main content by replacing fragments
Fragment fragment = new PlanetFragment();
Bundle args = new Bundle();
args.putInt(PlanetFragment.ARG_PLANET_NUMBER, position);
fragment.setArguments(args);
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(id.content_frame, fragment).commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
setTitle(mPlanetTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
@Override
public void setTitle(CharSequence title) {
mTitle = title;
getSupportActionBar().setTitle(mTitle);
}
