android-在带有SlidingDrawer的图形布局中,Eclpse 3.5和3.6中的ClassCastException

使用滑动抽屉时,是否有人在Eclipse 3.5或3.6中使图形布局正常工作？

我都收到以下错误：

错误！
ClassCastException：com.android.layoutlib.bridge.MockView无法转换为android.view.ViewGroup
异常详细信息记录在窗口>中显示视图>错误日志找不到以下类：
-滑动抽屉

我的代码和任何可以找到的示例代码都出现此错误：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#8CB69C">

    <SlidingDrawer
        android:id="@+id/drawer"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:handle="@+id/handle"
        android:content="@+id/content">

    <ImageView
        android:id="@id/drawerhandle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/drawerhandle"/>

    </SlidingDrawer>
</FrameLayout>

当我在设备上运行该应用程序时,它运行正常,没有任何问题,因此Android SDK 8,Eclipse 3.5和3.6或我的工作区都必须要解决这个问题,但我已经知道了.如果它对其他人有效,那一定是本地的.

提前致谢！！

解决方法:

我遇到了同样的错误,但事实证明我误解了XML文件中的自定义组件类路径.
因此,请检查SlidingDrawer类是否在同一包中,或者-最好-完全限定该类.例如,尝试：

< com.some.class.path.SlidingDrawer
android：id =“ @ id / drawer”

:java.lang.ClassCastException: android.widget.LinearLayout$LayoutParams cannot be cast to androi...

:java.lang.ClassCastException: android.widget.LinearLayout$LayoutParams cannot be cast to android.widget.RelativeLayout$LayoutParams

这个错首先说明：类型转化异常

解决方法：

一、详细检查是否将某种组件强制转换为另一种类型

二、本地声明类型是否与布局文件中的一致

三、获取的布局参数的父类和布局文件不一致

总之，要细心将布局文件类型与activity中的一致。

Android java.lang.ClassCastException：android.widget.LinearLayout无法强制转换为android.widget.TextView

我正在尝试打印listView中单击的值,但后来我得到以下异常：

07-04 10:40:56.482: E/AndroidRuntime(1356): FATAL EXCEPTION: main
07-04 10:40:56.482: E/AndroidRuntime(1356): java.lang.classCastException:      android.widget.LinearLayout cannot be cast to android.widget.TextView
07-04 10:40:56.482: E/AndroidRuntime(1356):     at com.passwordkeeper.ui.ActivityHomeScreen$1.onItemClick(ActivityHomeScreen.java:88)

这是一段代码：

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mTextView = (TextView) findViewById(R.id.labelList);
    db = new DatabaseHandler(this);
    createList();
    displayList();
}

createList函数正常工作.这是我的displayList方法：

public void displayList(){
    this.setlistadapter(new ArrayAdapter<String>(this, R.layout.activity_home_screen, R.id.listTextView, mAccountNames));
    mListView = getListView();
    mListView.setonItemClickListener(new OnItemClickListener(){
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
            String product = ((TextView) view).getText().toString();
            Log.v("mSelectedProduct", product);
        }           
    });
}

我的文件activity_home_screen.xml的xml代码是：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
    android:id="@+id/listTextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="28dp"
    android:layout_marginTop="26dp"
    android:textAppearance="?android:attr/textAppearanceLarge" />

任何帮助都会有用！

谢谢.

解决方法:

你可以试试这个

mListView.setonItemClickListener(new OnItemClickListener(){
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
            TextView txtview = (TextView)view.findViewById(R.id.listTextView);
            String product = txtview.getText().toString();
            Log.v("mSelectedProduct", product);
        }           
    });

Android java.lang.ClassCastException：无法将android.widget.RelativeLayout强制转换为android.widget.EditText

单击按钮将我从一个活动带到另一个活动时,我在Android中收到以下异常(我是Android开发中的新手,因此可能不是最聪明的问题)：

java.lang.classCastException: android.widget.RelativeLayout cannot be cast to android.widget.EditText

我试过几次清理项目,尝试过Android Tools中的Fix Project Properties选项,已经检查了xml中的错误,但似乎无法弄清楚.我不得不提到,在发生此异常之前,该按钮可以正常工作一段时间.

这是我的xml：

@H_301_17@
这是我在活动中引发异常的onCreate方法：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_customer_info);

    this.editMail = (EditText)findViewById(R.id.editCustomerEmail);
    this.editName = (EditText)findViewById(R.id.editCustomerName);
    this.editPhone = (EditText)findViewById(R.id.editCustomerPhone); // the exception points me here
}
@H_301_17@
解决方法:
您的代码说：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/editCustomerPhone"
@H_301_17@
editCustomerPhone是相对布局.

android studio NullPointerException at addDrawerListener 方法

如何解决android studio NullPointerException at addDrawerListener 方法？

我正在尝试构建一个包含少量项目的导航抽屉。但它让我在下面的代码中的 addDrawerListener 方法出错：

public class MainActivity extends AppCompatActivity {
    private DrawerLayout drawer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawer,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close);
        drawer.addDrawerListener(toggle);
        toggle.syncState();
    }

    @Override
    public void onBackpressed() {
        if (drawer.isDrawerOpen(GravityCompat.START)) {
            drawer.closeDrawer(GravityCompat.START);
        } else{
            super.onBackpressed();
        }
    }
}

这里是 AndroidManifest.xml :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapplication">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.MyApplication">
        <activity android:name=".MainActivity"
            android:theme="@style/Theme.MyApplication.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

这是菜单 ( drawer_menu.xml )，它似乎工作正常

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:showIn = "navigation_view">

        <item android:id="@+id/nav_people"
            android:icon="@drawable/ic_people"
            android:title="@string/people" />
        <item android:id="@+id/nav_goods"
            android:icon="@drawable/ic_goods"
            android:title="@string/goods" />
        <item android:id="@+id/nav_delivery"
            android:icon="@drawable/ic_delivery"

            android:icon="@drawable/ic_exit"
            android:title="@string/exit" />

    </group>
</menu>

还有一个标题（ nav_header.xml ），其中包含一张小图片和两个文本视图

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/nav_header"
    android:gravity="bottom"
    android:orientation="vertical"
    android:padding="16dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@mipmap/ic_launcher_round" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingTop="8dp"
        android:text="@string/strong_text"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/weak_text" />

</LinearLayout>

这里是 themes.xml 文件。我试图遵循的教程有点过时，并且有styles.xml 文件而不是themes.xml 但我不确定。我复制粘贴 <style name="Theme.MyApplication.NoActionBar">

中的 themes.xml (night) 部分

<resources xmlns:tools="http://schemas.android.com/tools">
    <!-- Base application theme. -->
    <style name="Theme.MyApplication" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
        <!-- Primary brand color. -->
        <item name="colorPrimary">@color/purple_500</item>
        <item name="colorPrimaryVariant">@color/purple_700</item>
        <item name="colorOnPrimary">@color/white</item>
        <!-- Secondary brand color. -->
        <item name="colorSecondary">@color/teal_200</item>
        <item name="colorSecondaryVariant">@color/teal_700</item>
        <item name="colorOnSecondary">@color/black</item>
        <!-- Status bar color. -->
        <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
        <!-- Customize your theme here. -->
    </style>

    <style name="Theme.MyApplication.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <item name="android:statusBarColor">@android:color/transparent</item>
    </style>

</resources>

解决方法

drawer 使用前需要初始化。

drawer = findViewById(R.id.drawer)

（注意：在 param 中，您需要像 Toolbar 一样从 xml 传递 DrawerLayout 的 id）。

这应该在你使用 drawer 之前，在你的案例下面的行之前。

ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawer,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close);
