Android - 没有抽屉视图发现重力左

标签： android

我正在尝试从右到左制作import UIKit class ViewController: UIViewController { @IBOutlet weak var lblGetMsg: UILabel! override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } @IBAction func btnGetMsg(sender: AnyObject) { let url = NSURL(string: "http://ip.jsontest.com") let task = NSURLSession.sharedSession().dataTaskWithURL(url!) {(data, response, error) in print(NSString(data: data!, encoding: NSUTF8StringEncoding)) self.lblGetMsg.text=(String(data: data!, encoding: NSUTF8StringEncoding)) } task.resume() } } 幻灯片。

我已经关注this tutorial，发现从左到右滑动的DrawerLayout非常令人满意。

当我将DrawerLayout的{​​{1}}更改为gravity时，它会从右向左滑动，但是，汉堡按钮不再正常工作，它会显示{{1}当我试图触摸它时。

这是修改后的切换功能

android.support.design.widget.NavigationView

那么..如何让汉堡按钮再次工作？

更新

这是主要布局的XML文件

right

这是我的主要课程

No drawer view found with gravity LEFT

2016年2月2日更新

尝试将抽屉视图更改为// Initializing Drawer Layout and ActionBarToggle drawerLayout = (DrawerLayout) findViewById(R.id.drawer); ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.openDrawer, R.string.closeDrawer){ @Override public void onDrawerClosed(View drawerView) { // Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank super.onDrawerClosed(drawerView); } @Override public void onDrawerOpened(View drawerView) { // Code here will be triggered once the drawer open as we dont want anything to happen so we leave this blank super.onDrawerOpened(drawerView); } //Added the lines below, tried solutions online but fail.. @Override public boolean onOptionsItemSelected(MenuItem item) { if (item != null && item.getItemId() == android.R.id.home) { if (drawerLayout.isDrawerOpen(Gravity.RIGHT)) { drawerLayout.closeDrawer(Gravity.RIGHT); } else { drawerLayout.openDrawer(Gravity.RIGHT); } } return false; } }; ..但这是一个坏主意，因为没有任何变化。试着将<?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/drawer" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" tools:context=".Activities.NewsfeedActivity"> <LinearLayout android:id="@+id/activity_newsfeed_wrapper" android:layout_height="match_parent" android:layout_width="match_parent" android:orientation="vertical" > <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/activity_newsfeed_toolbar" android:layout_width="match_parent" android:layout_height="@dimen/abc_action_bar_default_height_material" app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/> <FrameLayout android:id="@+id/activity_newsfeed_frame" android:layout_width="match_parent" android:layout_height="match_parent"> </FrameLayout> </LinearLayout> <android.support.design.widget.NavigationView android:id="@+id/activity_newsfeed_navigationView" android:layout_height="match_parent" android:layout_width="wrap_content" android:layout_gravity="right" app:headerLayout="@layout/drawer_header" app:menu="@menu/drawer" /> </android.support.v4.widget.DrawerLayout> 移到public class NewsfeedActivity extends AppCompatActivity { //Defining Variables private Toolbar toolbar;

fragmentTransaction.replace(R.id.activity_newsfeed_frame,fragment); fragmentTransaction.commit(); return true; // For rest of the options we just show a toast on click case R.id.b: Toast.makeText(getApplicationContext(),"b Selected",Toast.LENGTH_SHORT).show();

return true; case R.id.g: Toast.makeText(getApplicationContext(),"g Selected",Toast.LENGTH_SHORT).show(); return true; case R.id.h: Toast.makeText(getApplicationContext(),"h Selected",Toast.LENGTH_SHORT).show(); return true; default: Toast.makeText(getApplicationContext(),"Somethings Wrong",Toast.LENGTH_SHORT).show(); return true; } } }); // Initializing Drawer Layout and ActionBarToggle drawerLayout = (DrawerLayout) findViewById(R.id.drawer); ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.openDrawer, R.string.closeDrawer){ @Override public void onDrawerClosed(View drawerView) { // Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank super.onDrawerClosed(drawerView);

} }; //Setting the actionbarToggle to drawer layout drawerLayout.setDrawerListener(actionBarDrawerToggle); //calling sync state is necessay or else your hamburger icon wont show up actionBarDrawerToggle.syncState(); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.drawer, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here. The action bar will // automatically handle clicks on the Home/Up button, so long // as you specify a parent activity in AndroidManifest.xml. switch (item.getItemId()) { case android.R.id.home: if (drawerLayout.isDrawerOpen(Gravity.RIGHT)) { drawerLayout.closeDrawer(Gravity.RIGHT); } else { drawerLayout.openDrawer(Gravity.RIGHT); } return true; case R.id.action_settings: return true; } return super.onOptionsItemSelected(item); } } ，更糟糕的是因为没有滑动菜单..

尝试改变RIGHT

中的内容 
NavigationView

将LinearLayout更改为onOptionsItemSelected，“NOPE”，代码说明了......

在导航视图中尝试此操作

机器人：layout_gravity =＆＃34;端＆＃34;取代android：layout_gravity =＆＃34; right＆＃34; 

 <android.support.design.widget.NavigationView
        android:id="@+id/navigation_view"
        android:layout_height="match_parent"
        android:layout_width="wrap_content"
        android:layout_gravity="end"
        app:headerLayout="@layout/header"
        app:menu="@menu/drawer"
        />

//在java活动文件中添加这些行，它将起作用

 @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        switch (item.getItemId()) {
            case android.R.id.home:
                if (mDrawer.isDrawerOpen(Gravity.RIGHT)) {
                    mDrawer.closeDrawer(Gravity.RIGHT);
                } else {
                    mDrawer.openDrawer(Gravity.RIGHT);
                }
                return true;
            case R.id.action_settings:
                return true;
        }
final update:

我更改了示例项目中的一些行（MainActivity.java），现在它正在运行，使用此代码。

别忘了写android：layout_gravity =＆＃34; end＆＃34;代替android：layout_gravity =＆＃34; start＆＃34;在你的xml文件中。

答案 1 :(得分：0)

对于仍然存在此问题的任何人： 您应该在NavigationView中设置以下行：

android:layout_gravity="start"

，这在您的Java中：

ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close){
            @Override
            public boolean onOptionsItemSelected(MenuItem item) {
                if(item != null && item.getItemId() == android.R.id.home){
                    if (drawerLayout.isDrawerOpen((Gravity.END))) {
                        drawerLayout.closeDrawer(Gravity.END);
                    } else {
                        drawerLayout.openDrawer(Gravity.END);
                    }
                }
                return false;
            }
        };

对我有用。

        val drawerLayout:DrawerLayout = findViewById(R.id.drawer_layout)

        val navView:NavigationView = findViewById(R.id.nav_view)

        )
        setupActionBarWithNavController(navController, appBarConfiguration)

        navView.setupWithNavController(navController)

        val drawertoogle = ActionBarDrawerToggle (this,drawerLayout,toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close)

        drawertoogle.isDrawerIndicatorEnabled = false

        drawertoogle.setToolbarNavigationClickListener 
            drawerLayout.openDrawer(GravityCompat.END)
        }
