SlidingMenu拖拽出来是白板,怎么办?

MainActivity如下:

package com.wuzhiqiang.learnslidingmenu;

import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.KeyEvent;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;

import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu;

public class MainActivity extends AppCompatActivity {

    private SlidingMenu slidingMenu;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });


        slidingMenu = new SlidingMenu(this);
        slidingMenu.setMode(SlidingMenu.LEFT);//设置模式,在左边
        slidingMenu.setBehindOffset(R.dimen.sliding_menu_offset);//设置出来的宽度
        slidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);//设置全屏都可触摸拖出
        slidingMenu.attachToActivity(this,SlidingMenu.SLIDING_CONTENT);//绑定当前activity
        slidingMenu.setMenu(R.layout.sliding_menu);//绑定布局视图
    }

//重写KeyDown方法,绑定菜单按键拉出SlidingMenu
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        switch (keyCode) {
            case KeyEvent.KEYCODE_MENU:
                slidingMenu.toggle(true);
                break;
            default:
                break;
        }
        return super.onKeyDown(keyCode, event);
    }
}

sliding_menu.xml代码如下:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ff8990">

    <com.jeremyfeinstein.slidingmenu.lib.SlidingMenu
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/slidingmenu">

        <Button
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Check me!"
            android:background="#0f0"/>
    </com.jeremyfeinstein.slidingmenu.lib.SlidingMenu>
</LinearLayout>

androidStudio配置方法:把SlidingMenu_master中的Library,复制到项目下的libraries目录下,修改library的build.gradle,修改项目下的setting.gradle。

library下build.gradle如下:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'
    }
}
apply plugin: 'android-library'

dependencies {
    compile 'com.android.support:support-v4:13.0.0'
}

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }

    sourceSets {
        main {
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']

            manifest.srcFile 'AndroidManifest.xml'
        }
    }

}

app下build.gradle如下:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.wuzhiqiang.learnslidingmenu"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.0'
    compile 'com.android.support:design:23.1.0'
    compile project(':library')
}

setting.gradle如下:

include ':app',':library'
project(':library').projectDir = new File('libraries/library')

运行效果如下:

问题解决了!
因为我之前是手动把SlidingMenu中的library添加到项目路径下,再修改配置文件,这中间不知道出了什么问题。
昨天我重新写了这个程序,让AS自动添加librayr,然后修改一些配置,它就行了!!1

SlidingMenu的GitHub主页这样讲,为了实现sliding menu,有两种办法,其一:直接在Activity内new一个sliding menu然后添加到activity内,就是你的做法;其二,继承SlidingActivity。

链接:方法一是这样描述的: How to Integrate this Library into Your Projects

You can wrap your Activities in a SlidingMenu by constructing it programmatically (new SlidingMenu(Context context)) and then calling SlidingMenu.attachToActivity(Activity activity, SlidingMenu.SLIDING_WINDOW | SlidingMenu.SLIDING_CONTENT). SLIDING_WINDOW will include the Title/ActionBar in the content section of the SlidingMenu, while SLIDING_CONTENT does not. You can check it out in the example app AttachExample Activity.

你的做法哪儿出了问题呢?我们从上面这段话提到的AttachExample.java看起:

// AttachExample.java
// onCreate()
        // configure the SlidingMenu
        menu = new SlidingMenu(this);
        menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
        menu.setShadowWidthRes(R.dimen.shadow_width);
        menu.setShadowDrawable(R.drawable.shadow);
        menu.setBehindOffsetRes(R.dimen.slidingmenu_offset);
        menu.setFadeDegree(0.35f);
        menu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT);
// 上面的代码,是你配置过的,
// 需要特别注意以下的代码:
        menu.setMenu(R.layout.menu_frame);
        getSupportFragmentManager()
        .beginTransaction()
        .replace(R.id.menu_frame, new SampleListFragment())
        .commit();

先来看下R.layout.menu_frame是什么:


<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/menu_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

这只是一个空的布局,你可以把它当做一个Fragment的容器。SlidingMenu提前注册了一个空的布局,需要你用自己的menu去替换它:.replace(R.id.menu_frame, new SampleListFragment())

你并没有替换,所以看到的是空的。
这种做法的本质是把一个包含menu的Fragment视图添加给Activity。

别用slidingmenu了,自带的drawerlayout真的很好用
