我创建了一个自定义TextView,我唯一做的就是在布局xml中放置一个“实例”.
这会导致应用程序崩溃并出现“Inflate Exception”：
这会导致应用程序崩溃并出现“Inflate Exception”：
package com.example.TestApp;
...
public class MyTextView extends TextView {
public MyTextView (Context context) {
super(context);
}
@Override
protected void onMeasure(int widthMeasureSpec,int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec,heightMeasureSpec); }
@Override
public void onDraw(Canvas canvas) {
super.onDraw(canvas);
}
}
完整的布局文件：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.example.TestApp.MyTextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello World,MyActivity"
/>
</LinearLayout>
日志是：

我已经阅读了很多关于这些膨胀例外情况的帖子,但这一次它确实是最简单的案例. xml(com.example.TestApp.MyTextView)中使用的类路径似乎是正确的 – Intellj IDEA甚至建议它……
顺便说一句：最小目标sdk版本设置为10.
