Android APP开发中运行中的坑

1、运行报错

尝试了DeepSeek多种解决方案，发现原因在于引入的lib包版本不匹配导致，替换对应Android版本jar包

implementation(fileTree("libs") { include("*.jar") })

2、SwipeRefreshLayout 与 CoordinatorLayout 嵌套刷新

XML 复制代码

<androidx.coordinatorlayout.widget.CoordinatorLayout 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:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        tools:context=".TestActivity">

    <com.google.android.material.appbar.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/appbar_layout"
        android:fitsSystemWindows="true">
        <com.google.android.material.appbar.MaterialToolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize" />
    </com.google.android.material.appbar.AppBarLayout>

    <androidx.swiperefreshlayout.widget.SwipeRefreshLayout
        android:id="@+id/srl_refresh_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/rv_devices"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

</androidx.coordinatorlayout.widget.CoordinatorLayout>

SwipeRefreshLayout 作为最外层布局
CoordinatorLayout 作为第二次布局
CoordinatorLayout 中嵌套 AppBarLayout 及 ListView 或 RecyclerView 注意 app:layout_behavior="@string/appbar_scrolling_view_behavior", 由于 CoordinatorLayout 是 FrameLayout 子类因此 app:layout_behavior 为必要属性，否则无法正常显示

3、`ActivityMainBinding的使用`

ActivityMainBinding.inflate()方法默认绑定的是与当前Activity关联的布局文件（如activity_main.xml），但可以通过以下方式间接实现指定布局的功能‌

自动生成的Binding类名称遵循<布局文件名>Binding规则，例如activity_other.xml会生成ActivityOtherBinding

4、布局从状态看顶部开始布局

复制代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:id="@+id/settings"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"/>
</LinearLayout>

android:fitsSystemWindows="true" 是 Android 布局中用于处理系统窗口（如状态栏、导航栏）与应用内容区域关系的关键属性，其核心作用和行为如下：

‌自动调整内边距‌

当设置为 true 时，系统会为该 View 添加与系统窗口（状态栏/导航栏）等高的 padding，避免内容被遮挡24。

示例：若状态栏高度为 24dp，View 的顶部会自动增加 24dp 的 padding16。

‌生效条件‌

仅对 ‌非嵌入型 Activity‌ 的根布局有效（如普通 Activity，非 Fragment 或 Dialog）27。

需配合透明状态栏/导航栏使用（如 android:windowTranslucentStatus=true）56。

5、CursorLoader刷新问题

使用CursorLoader时，在onLoadFinished中不要关闭Cursor，系统会自动关闭，否者存在不刷新的情况

复制代码

    public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
        Log.i(TAG,"onLoadFinished = " +cursor.toString());
        messageList.clear();
        if (cursor != null) {
            try {
                if (cursor != null && cursor.moveToFirst()) {
                    do {
                        final String content = cursor.getString(cursor.getColumnIndex(MessageContract.MessageEntry.COLUMN_CONTENT));
                        final String sender = cursor.getString(cursor.getColumnIndex(MessageContract.MessageEntry.COLUMN_SENDER));
                        final String device = cursor.getString(cursor.getColumnIndex(MessageContract.MessageEntry.COLUMN_DEVICE));
                        final long timestamp = cursor.getInt(cursor.getColumnIndex(MessageContract.MessageEntry.COLUMN_TIMESTAMP));
                        final boolean isSent = (cursor.getInt(cursor.getColumnIndex(MessageContract.MessageEntry.COLUMN_IS_SENT)) != 0) ? true: false;
                        Message message = new Message(content,  sender,  device,  timestamp,  isSent);
                        messageList.add(message);
                    } while (cursor.moveToNext());
                }
            } finally {
//                cursor.close();
            }
        }
        messagesAdapter.notifyDataSetChanged();
    }

6、ConstraintLayout 中 adjustResize不生效

最下部的EditText无法点击后键盘覆盖了EditText，不向上挤压，解决方案，在ConstraintLayout中添加android:fitsSystemWindows="true"

复制代码

<androidx.constraintlayout.widget.ConstraintLayout
    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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

7、ConstraintLayout layout_marginStart无效

未设置 layout_constraintStart_toStartOf 或 layout_constraintEnd_toEndOf 等水平约束时，marginStart 不会生效

8、Android studio Clip art无法使用

删除图标元数据缓存文件‌

定位到Android SDK安装目录下的icons/material文件夹（例如：C:\Users\用户名\AppData\Local\Android\Sdk\icons\material）3

删除其中的icons_metadata.txt文件

重启Android Studio后打开Vector Asset窗口，Clip Art图标即可正常显示

9、CheckBox 设置 android:button不生效

必须正确设置 buttonTint 和 backgroundTint 为 @null 才能让自定义背景生效。参考如下

彻底解决Android中CheckBox和Button自定义背景无效问题：关键属性解析与实践_android checkbox 自定义样式不生效-CSDN博客

10. RecyclerView 设置Item onClick不生效

最终发现是在Cusorload中的onLoadFinished调用修改数据库markUnread(mDevice.getIp());操作导致刷新频繁，ItemOnclick不生效

java 复制代码

    public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
        Log.i(TAG,"onLoadFinished = " +cursor.toString());
        SwapCusorAdapter(cursor);
        markUnread(mDevice.getIp());
        messagesAdapter.notifyDataSetChanged();
        scrollToBottom();
    }
