Android studio EditText clickable
This question already has an answer here:
将android:focusableInTouchMode =“true”设置为您的根布局
    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/blue_dark"
        android:focusableInTouchMode="true"
        android:orientation="vertical">
        .
        .
        .
    </RelativeLayout>
只需在你的清单文件中写入
<activity
        android:name=".YourActivity"
        android:windowSoftInputMode="adjustPan|stateAlwaysHidden" />
