Do not concatenate text displayed with setText，use resource string with placeholders.

General warning ：

You should use resource strings to display text placeholders

And in xml The warning that Chinese characters are written directly in the layout means

String splicing is also good , Chinese characters written directly are also good ,

It should be in strings.xml Declaration in the document , Then the reference

for example：

layout.xml File reference

strings.xml Declaration in the document

About variable splicing parameters

such as ：

mTextView.setText(" There is still... Before the Chinese New Year "+mDay+" God "+mMinute+" when "+mSecond+" second ");

Copy

Statement ：

<string name="delay_time"> There is still... Before the Chinese New Year %1$d God %2$d when %3$d second </string>

Copy

Use in code :

mTextView.setText(String.format(getResources().getString(R.string.delay_time),mDay,mMinute,mSecond));

Copy
