Question

我想实现导航抽屉，当我滑动时它工作得很好但是在点击ImageView时它没有打开我的代码如下所示 MainActivity

mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
imgMenu = (ImageView) findViewById(R.id.imgMenu);

        imgMenu.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mDrawerLayout.isDrawerOpen(GravityCompat.START);
            }
        });

nav_drawer_material.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/app_bar_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer" />

</android.support.v4.widget.DrawerLayout>

app_bar_main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <include layout="@layout/home_details" />

</android.support.design.widget.CoordinatorLayout>

在home_details中，我已经

了

<ImageView
                android:id="@+id/imgMenu"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:padding="@dimen/padding_10"
                android:src="@drawable/ic_menu" />

Answer 1

isDrawerOpen仅检查抽屉是否打开。改为使用openDrawer方法。

Answer 2

mDrawerLayout.isDrawerOpen(GravityCompat.START)实际上会告诉您抽屉的状态，并且不会改变抽屉的状态。

要更改抽屉的状态，请将该行替换为mDrawerLayout.openDrawer(GravityCompat.START)。

Answer 3

尝试这个...

mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
imgMenu = (ImageView) findViewById(R.id.imgMenu);

        imgMenu.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                mDrawerLayout.openDrawer(GravityCompat.START);
            }
        });

单击ImageView时导航抽屉未打开
