问题描述

我在Relative layout中面临问题.我在XML布局中设置了几个textviews，但是在运行程序it will not show the text on emulator/phone之后.在我思考之前，这是android studio更新版本的问题.但是我还检查了另一台具有较旧android版本的计算机系统.我正在与大家共享XML代码.请帮我.

I am facing Problem In Relative layout. I set several textviews in my XML layout but after running the program, it will not show the text on emulator/phone. Before I was thinking, this is the problem of the updated version of android studio. But I had also checked in another computer system with an older android version. I am sharing the XML code with you all. Please Help me.

推荐答案

您正在textView中使用tools:text="Ramesh Singha"，用于测试目的.如果要设置文本，则应使用以下选项

You are using tools:text="Ramesh Singha" in textView and that is used for testing purpose. You should use following options if you want to set text

1. android:text="Ramesh Singha"

添加代码

<TextView
     android:id="@+id/tv_emp_name"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:textSize="24sp"
     android:textColor="#262d3d"
     android:letterSpacing="0.02"
     tools:text="Ramesh Singha"
     android:fontFamily="@font/roboto_slab_bold"
     android:layout_below="@id/imgv_boss"
     android:layout_centerInParent="true"
     android:layout_marginTop="26dp" />

TextView userName=(TextView)findViewById(R.id.tv_emp_name)
userName.setText("Ramesh Singha")
