I. Error description

To achieve the effect of TextView, I wrote a class of MyTextView to inherit TextView. The result is an error when calling the XML page of layout.

The class structure is as follows:

The error message is as follows:

The error area code is as follows:

/TextViewDemo1/res/layout/activity04.xml

Fry. MyTextView

 1 package fry; 2  3 import android.content.Context; 4 import android.util.AttributeSet; 5 import android.widget.TextView; 6  7 public class MyTextView extends TextView{ 8  9     public MyTextView(Context context, AttributeSet attrs, int defStyle) {10         super(context, attrs, defStyle);11         // TODO Auto-generated constructor stub12     }13 14     public MyTextView(Context context, AttributeSet attrs) {15         super(context, attrs);16         // TODO Auto-generated constructor stub17     }18 19     public MyTextView(Context context) {20         super(context);21         // TODO Auto-generated constructor stub22     }23     24     @Override25     public boolean isFocused() {26         // TODO Auto-generated method stub27         return true;28     }29     30 }

 

Ii. Solution

InflateException: Bin file line #19: Error inflating class MyTextView

This statement indicates that the MyTextView class is incorrect,

/TextViewDemo1/res/layout/activity04.xml

1 <MyTextView2 android: id = "@ + id/TV _runHorseLamp1" 3 android: layout_width = "match_parent" 4 android: layout_height = "wrap_content" 5 android: ellipsize = "marquee" 6 android: singleLine = "true" 7 android: text = "this is a long and mighty rolling text that achieves the effect of running the horse lamp. It has a very high meaning and strong cultivation." 8/>

We can see that the class name is used directly, and the referenced class name in XML must contain the package name,

So we changed the first line of the above Code to fry. MyTextView.

The implementation result is as follows:
