Why keyboard is overlap on the AutoCompleteTextView when inside ScrollView

Question

I have a simple android layout and code, but the keyboard always overlap my AutoCompleteTextView when I click it. Note : The AutoCompleteTextView when inside ScrollView. Note : platform is 6.0.1

package com.example.jason_wu.search;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.AutoCompleteTextView;

public class Main2Activity extends AppCompatActivity {
    private AutoCompleteTextView mAtv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);
        mAtv = (AutoCompleteTextView) findViewById(R.id.location_auto_complete);
        //issue 1
        //mAtv.setBackground(getDrawable(R.drawable.search_input_focus));
        //issue 2
        mAtv.setHeight(300);
    }
}

and my AndroidManifest.xml here:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.jason_wu.search">

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity
        android:name="com.example.jason_wu.search.Main2Activity"
        android:windowSoftInputMode="adjustPan"
        >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Try limiting the dropdown items to show

One way is you can Limit the dropdown items to show. But there's no such proper way of it to show number of maximumSuggestions option, But the trick you can apply is Get the height of one of the rows and multiply it (number of rows to show) times and use setDropDownHeight() to set its height.

There is a method setDropDownHeight of AutoCompleteTextView class. You can see them and use.

If you are confused or not sure of height of suggestions items you can customize this. Have a look how to set custom height.
