由于图像太多（仅20张图像），无法在Note 2上运行App

从“主活动”页面转到“新活动”页面时出现以下错误。新活动页面崩溃，除非它有＆lt; 10张图片左右，这很可怜（但是我的计算机上运行的应用程序运行得很好）：

据我所知，当处理过多位图时，手机的内存耗尽时会发生内存不足错误。

是的，我已阅读Android开发人员网页上有关处理位图的提示。但是，我仍然不明白我应该插入哪些代码组，以及我应该插入的代码。我已经尝试将他们的一些东西插入我的.java文件，但我最终得到错误。我认为这是我作为Java的初学者而不了解如何应用示例代码。

同样，我是Java和Android Studio的初学者，所以请尽可能简单地向我解释并尽可能简单地解释一下。

这是我的代码：

MainActivity.java：

package com.example.matthew.test1;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.ImageButton;

public class MainActivity extends AppCompatActivity {
//Main Menu

    //Main Activity Mario Icon:

    ImageButton Mario;
    ImageButton Luigi;

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

        Mario= (ImageButton) findViewById(R.id.Mario);

        Mario.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intentLoadNewActivity = new Intent(MainActivity.this, NewActivity.class);
                startActivity(intentLoadNewActivity);

            }
        });

       Luigi= (ImageButton) findViewById(R.id.Luigi);

        Luigi.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intentLoadNewActivity = new Intent(MainActivity.this, Main2Activity.class);
                startActivity(intentLoadNewActivity);


            }
        });
    }



}

NewActivity.java：

public class NewActivity extends AppCompatActivity implements View.OnClickListener {

    ViewFlipper viewFlipper;
    Button next;
    Button previous;
    TextView pageCounter;
    int count = 1;
    private static final int TOTAL_IMG_COUNT = 23;

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

        viewFlipper = (ViewFlipper)findViewById(R.id.viewFlipper);
        next = (Button) findViewById(R.id.next);
        previous = (Button) findViewById(R.id.previous);
        pageCounter = (TextView)findViewById(R.id.textView2);
        pageCounter.setText(String.valueOf(count));
        next.setOnClickListener(this);
        previous.setOnClickListener(this);
    }
    @Override
    public void onClick(View v) {
        if (v == next) {
            viewFlipper.showNext();
            if (next.getId() == (R.id.ImageView23)) {
                count = 1;
            } else {
                count++;
            }
            pageCounter.setText(String.valueOf(count) + "/" + TOTAL_IMG_COUNT);
        }
        else if (v == previous) {
            viewFlipper.showPrevious();
            if(previous.getId() == (R.id.ImageView1)) {
                count = TOTAL_IMG_COUNT;
            } else {
                count--;
            }
            pageCounter.setText(String.valueOf(count) + "/" + TOTAL_IMG_COUNT);
        }
    }
}
