我正在开发一个Android项目,我正在尝试使用http://developer.android.com/training/implementing-navigation/nav-drawer.html中的示例集成新的导航抽屉。
除了一件事之外它主要工作,动作栏向上按钮不显示菜单,但如果我从边缘在主活动屏幕上滑动我的手指,则菜单出现,所以我知道没有任何问题实际菜单,它只是操作栏按钮。
以下是代码
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mTitle;
private CharSequence mDrawerTitle;
private String[] mPlanetTitles;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = mDrawerTitle = getTitle();
mPlanetTitles = getResources().getStringArray(R.array.planets_array);
mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);
mDrawerList = (ListView)findViewById(R.id.left_drawer);
MenuItemAdapter menuAdapter = new MenuItemAdapter(this);
menuAdapter.add(new MenuItem("Hello"));
menuAdapter.add(new MenuItem("World"));
menuAdapter.add(new MenuItem("Parsnips"));
menuAdapter.add(new MenuItem("Turnips"));
mDrawerList.setAdapter(menuAdapter);
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(
this,
mDrawerLayout,
R.drawable.ic_drawer,
R.string.drawer_open,
R.string.drawer_closed)
{
public void onDrawerClosed(View view)
{
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView)
{
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null)
{
selectItem(0);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
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
android.app.Fragment fragment = new PlanetFragment();
Bundle args = new Bundle();
args.putInt(PlanetFragment.ARGS_PLANET_NUMBER, position);
fragment.setArguments(args);
android.app.FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
setTitle(mPlanetTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
@Override
public void setTitle(CharSequence title)
{
mTitle = title;
getActionBar().setTitle(mTitle);
}
@Override
protected void onPostCreate(Bundle savedInstanceState)
{
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
public static class PlanetFragment extends android.app.Fragment
{
public static final String ARGS_PLANET_NUMBER = "planet_number";
public PlanetFragment()
{
}
@Override
public View onCreateView(LayoutInflater inflator, ViewGroup container, Bundle savedInstanceState)
{
View rootView = inflator.inflate(R.layout.fragment_planet, container, false);
int i = getArguments().getInt(ARGS_PLANET_NUMBER);
String planet = getResources().getStringArray(R.array.planets_array)[i];
//((TextView)rootView.findViewById(R.id.fragment_text_view)).setText(planet);
getActivity().setTitle("Planet: " + planet);
return rootView;
}
}
private class MenuItem
{
public String menuName;
public MenuItem(String menuName)
{
this.menuName = menuName;
}
}
public class MenuItemAdapter extends ArrayAdapter<MenuItem>
{
public MenuItemAdapter (Context context)
{
super(context,0);
}
public View getView (int position, View convertView, ViewGroup parent)
{
convertView = null;
if (convertView == null)
{
convertView = LayoutInflater.from(getContext()).inflate(R.layout.row_menu_item, null);
}
/*TextView title = (TextView)convertView.findViewById(R.id.row_title);
title.setText(getItem(position).menuName);
title.setVisibility(View.VISIBLE);*/
EditText title = (EditText)convertView.findViewById(R.id.row_edittext);
title.setHint(getItem(position).menuName);
title.setVisibility(View.VISIBLE);
return convertView;
}
}
}
感谢您提供的任何帮助。

您忘记实施onOptionsItemSelected
这就是魔术发生的地方:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Pass the event to ActionBarDrawerToggle, if it returns
// true, then it has handled the app icon touch event
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
// Handle your other action bar items...
return super.onOptionsItemSelected(item);
}

对于那些仍然遇到麻烦的人,你可能会错过这种方法(OP有,但我删除了):
max_execution_time(0);
答案 2 :(得分:2)
它为我工作。
drawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mDrawer.openDrawer(GravityCompat.START);
}
});

在这里,我将告诉你在不使用android studio的情况下在Android中创建抽屉导航的简单方便。我刚刚使用ADT创建导航抽屉。 这是代码看看
activity_main.xml中
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/dr_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:id="@+id/mainContent"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="@+id/txt1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="swipe content"/>
<Button
android:id="@+id/bt1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text = "Click to open d"/>
</RelativeLayout>
<RelativeLayout
android:id="@+id/drawer"
android:layout_width="200dp"
android:layout_height="match_parent"
android:layout_gravity = "start"
android:background="#FFFFFF">
<TextView
android:id="@+id/txt2"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:text="drawer content are here arr"/>
<Button
android:id="@+id/bt2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text = "Click to open d"/>
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
MainActivity.java
package com.example.drawer1;
import android.os.Bundle;
import android.annotation.SuppressLint;

public class MainActivity extends Activity {
private DrawerLayout drawerLayout;
private View drawerView;
Button bt1,bt2;
private DrawerListener myDrawerListner;
private ActionBarDrawerToggle mDrawerTogle;
@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
drawerLayout = (DrawerLayout) findViewById(R.id.dr_layout);
drawerView = (View) findViewById(R.id.drawer);
drawerLayout.setDrawerListener(myDrawerListner);
bt1 = (Button) findViewById(R.id.bt1);
bt2 = (Button) findViewById(R.id.bt2);
mDrawerTogle =new ActionBarDrawerToggle(this, drawerLayout,
R.drawable.ic_drawer,R.string.open_drawer,R.string.close_drawer){
public void onDrawerOpened(View drawerView) {
// TODO Auto-generated method stub
super.onDrawerOpened(drawerView);
getActionBar().setTitle("SpeakEng");
}
public void onDrawerClosed(View view) {
// TODO Auto-generated method stub
super.onDrawerClosed(view);
getActionBar().setTitle("SpeakEng");
}
};
drawerLayout.setDrawerListener(mDrawerTogle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
bt2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
drawerLayout.closeDrawer(drawerView);
}
});
bt1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
drawerLayout.openDrawer(drawerView);
}
});
}
@Override
public void onConfigurationChanged(Configuration newConfig){
super.onConfigurationChanged(newConfig);
mDrawerTogle.onConfigurationChanged(newConfig);
}
public boolean onOptionsItemSelected(MenuItem item){
if (mDrawerTogle.onOptionsItemSelected(item)){
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
protected void onPostCreate(Bundle savedInstanceState){
super.onPostCreate(savedInstanceState);
//Sync the toogle state after onRestoreInstanceState has occured.
mDrawerTogle.syncState();
}
}
您可以通过单击按钮打开抽屉1),2)从左侧拉动,3)点击操作栏上的抽屉图标。如果您希望可以打开它。我给了您三个选项。
注意:drawerLayout必须是root元素,如代码所示。 并保持onConfigurationChanged(),onOptionsItemSelected(),onPostCreate()。 这三种方法对于创建导航抽屉非常重要。
祝你好运!。
