java - 当我在较小的设备上运行程序时，如何删除 imageView

Question

所以我有这个应用程序，当我在较小的设备上运行它时，我想删除 Logo ，因为它会压迫用户界面的其余部分并使事情看起来很奇怪。这是我制作的第一个应用程序，所以不知道如何完成此任务。

这是我的 main_activity 代码:

package no.flammbaert.flammbaert;

import android.app.Activity;
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageButton;
import android.widget.Button;


public class MainActivity extends Activity implements View.OnClickListener{
    ImageButton btn_settings;
    ImageButton btn_voksen;
    ImageButton btn_barn;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Init();
    }

    @Override
    public void onClick(View v) {
        if(v.getId() == btn_voksen.getId()){
            Intent i = new Intent(MainActivity.this, VoksenActivity.class);
            startActivity(i);
        }

        if(v.getId() == btn_settings.getId()){
            Intent i = new Intent(MainActivity.this, Preferences.class);
            startActivity(i);
        }

        if(v.getId() == btn_barn.getId()){
            Intent i = new Intent(MainActivity.this, BarnActivity.class);
            startActivity(i);
        }
    }

    public void Init(){
        btn_settings = (ImageButton)findViewById(R.id.btn_settings);
        btn_voksen = (ImageButton) findViewById(R.id.btn_voksen);
        btn_barn = (ImageButton) findViewById(R.id.btn_barn);
        btn_settings.setOnClickListener(this);
        btn_voksen.setOnClickListener(this);
        btn_barn.setOnClickListener(this);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            Intent i = new Intent(MainActivity.this, Preferences.class);
            startActivity(i);

            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

这是 xml 文件:

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity"
    android:background="@drawable/bg_blue_sky">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/relativeLayout"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_above="@+id/btn_settings">

        <ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/btn_barn"
            android:background="@drawable/knapp_1"
            android:layout_below="@+id/imageView"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:layout_marginBottom="10dp" />


        <ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/btn_voksen"
            android:background="@drawable/knapp_2"
            android:layout_below="@+id/btn_barn"
            android:layout_alignLeft="@+id/btn_barn"
            android:layout_alignStart="@+id/btn_barn"
            />


        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/imageView"
            android:background="@drawable/logo_flammbaert"
            android:layout_alignParentTop="true"
            android:layout_centerHorizontal="true"
            android:layout_marginBottom="20dp"
            android:scaleType="fitCenter"
            android:adjustViewBounds="true"/>



    </RelativeLayout>

    <ImageButton
        android:id="@+id/btn_settings"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:background="@drawable/gear"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:layout_marginRight="10dp"
        android:scaleType="fitXY"/>
</RelativeLayout>

感谢您的帮助。

我认为您可以使用以下代码 fragment 检查应用程序是否在小屏幕或大屏幕上运行。

 Configuration config = getResources().getConfiguration();
            if((config.screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) ==  
                Configuration.SCREENLAYOUT_SIZE_SMALL) 
            {
                //small screen
// Here you can remove/invisible the image view by using 
imageView.setVisible(View.GONE);

            }
