Logcat没有指出错误行，我贴出相关代码

我在 DrawerLayout 遇到非法参数异常，必须在运行时使用 MeasureSpec.Exactly 进行测量。

BaseActivity.java:

  private ListView mDrawerList;
  private DrawerLayout mDrawerLayout;
  private ArrayList<Chapter> chapterArray;
  ChapterListAdapter adapter;
  SqliteDbHelper dbHelper;


  dbHelper = new SqliteDbHelper(this);

  dbHelper.openDataBase();

  LayoutInflater mInflater = (LayoutInflater) getApplicationContext()
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

  View mCustomView = mInflater.inflate(R.layout.custom_actionbar, null); 

  mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
  mDrawerList = (ListView) findViewById(R.id.list_menu);

  chapterArray=new ArrayList<Chapter>();
  chapterArray=dbHelper.getChapterDetails();

  adapter = new ChapterListAdapter(this,chapterArray);
  mDrawerList.setAdapter(adapter);

custom_actionbar.xml:

<?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"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#5467F7">

        <TextView
            android:id="@+id/title_text"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:gravity="center"
            android:text="Chapters"
            android:textColor="#FFFFFF"
            android:textStyle="bold" />

    </RelativeLayout>

    <ListView
        android:id="@+id/list_menu"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#E36666"
        android:choiceMode="singleChoice"
        android:dividerHeight="1dp"
        />

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

我不知道如何解决这个问题。任何人都可以帮助我解决这个问题。谢谢。

Answer 1

错误:

Illegal Argument Exception - DrawerLayout must be measured with MeasureSpec.EXACTLY

根据错误日志，我可以建议创建自定义类来扩展 DrawerLayout 并强制执行正确的 Measure_Specs:

public class MyDrawerLayout extends DrawerLayout {

    public MyDrawerLayout(Context context) {
        super(context);
    }

    public MyDrawerLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyDrawerLayout(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        widthMeasureSpec = MeasureSpec.makeMeasureSpec(
                MeasureSpec.getSize(widthMeasureSpec), MeasureSpec.EXACTLY);
        heightMeasureSpec = MeasureSpec.makeMeasureSpec(
                MeasureSpec.getSize(heightMeasureSpec), MeasureSpec.EXACTLY);
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }

}

或作为临时解决方法，尝试将 layout_width 和/或 layout_height 设置为特定大小(例如 500dp)，而不是 match_parent。

编辑:

BaseActivity.java

import com.steve.database.MyDrawerLayout;

private MyDrawerLayout mDrawerLayout;
private ListView mDrawerList;


LayoutInflater mInflater = (LayoutInflater) getApplicationContext()
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

View mCustomView = mInflater.inflate(R.layout.custom_actionbar, null);

mDrawerLayout = (MyDrawerLayout)mCustomView.findViewById(R.id.drawer_layout);
mDrawerList = (ListView)mCustomView.findViewById(R.id.list_menu);
