[![This is Image of edit_note activity. Here content text is not showing][1]][1]After opening notes I see textview of my note&#39;s title and content. I want to edit notes. But there is a problem with the edit note activity. It shows only the text of title in edittext. But below this content text not shown. I tried many ways like I tried to check what&#39;s a problem I put data of title. But it is also not showing the title. Means upper title edit text can show title data and content data but second edit text doesn&#39;t show title data and content data.

# 答案1
**得分**: 2
你的编辑文本赋值是错误的：
```java
edit_note = findViewById(R.id.edit_note);

而应该改为：
edit_note = findViewById(R.id.edit_content);


英文:
Your edittext assigning is wrong :
edit_note =  findViewById(R.id.edit_note);

Instead it needs :
edit_note =  findViewById(R.id.edit_content);
