如何在android中創建照片應用程序？

我的程序將不再運行。它只是迫使關閉。我之前有兩張照片，我從互聯網上下載並放在我的可繪製文件夾中。但我刪除了雖然並添加了一些我從旅途中拍攝的照片。我更新了XML和Java代碼，但現在它不會打開。這是我的代碼。如何在android中創建照片應用程序？

package com.example.photoalbum;

import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 
import android.widget.ImageView; 


public class DisplayPhotos extends Activity 
{ 
ImageView iv1, iv2, iv3, iv4; 
private Integer [] imageArray = {R.drawable.nepal1, 
R.drawable.nepal2,R.drawable.nepal3, R.drawable.nepal4}; 

int imageCount = 0; 

//******************onCreate()******************************* 
@Override 
public void onCreate(Bundle b) 
{ 
    super.onCreate(b); 
    setContentView(R.layout.activity_display_photos); 
    Button btn1 = (Button) findViewById(R.id.previous_btn); 
    Button btn2 = (Button) findViewById(R.id.next_btn); 
    iv1 = (ImageView) findViewById(R.id.nepal1); 
    iv2 = (ImageView) findViewById(R.id.nepal2); 
    iv3 = (ImageView) findViewById(R.id.nepal3); 
    iv4 = (ImageView) findViewById(R.id.nepal4); 
    ImageView imgs [] = new ImageView[4]; 
    imgs[0] = iv1; 
    imgs[1] = iv2; 
    imgs[2] = iv3; 
    imgs[3] = iv4; 

    showImage(); 
} 
//*************************showImage()********************* 
public void showImage() 
{ 
    iv1.setImageResource(imageArray[imageCount]); 
} 


//***************************doit************************** 
    public void doit(View v) 
{ 
    switch (v.getId()) 
    { 
     case (R.id.previous_btn): 
      imageCount--; 
      if (imageCount == -1) 
       imageCount = 3; 
      showImage(); 
      break; 

     case (R.id.next_btn): 
      imageCount++; 
      if (imageCount == 4) 
       imageCount = 0; 
      showImage(); 
      break; 
    } 
} 
}

我的XML代碼

<FrameLayout xmlns:android= 
"http://schemas.android.com/apk/res/android" 
android:orientation="vertical" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" > 

<ImageView 
    android:id="@+id/nepal1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" /> 

<ImageView 
    android:id="@+id/nepal2" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"/> 
<ImageView 
    android:id="@+id/nepal3" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"/> 
<ImageView 
    android:id="@+id/nepal4" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" /> 

    <Button 
     android:id="@+id/previous_btn" 
     android:layout_width="163dp" 
     android:layout_height="wrap_content" 
     android:layout_gravity="bottom|left" 
     android:onClick="doit" 
     android:text="@string/previous" /> 

    <Button 
     android:id="@+id/next_btn" 
     android:layout_width="163dp" 
     android:layout_height="wrap_content" 
     android:layout_gravity="bottom|right" 
     android:onClick="doit" 
     android:text="@string/next" /> 

</FrameLayout>

可能是您的新圖像是太大了，你的應用程序試圖分配55987216個字節，它導致內存分配例外。看看一些處理圖片/照片的android libraries like picasso。

有關更多詳細信息和其他選項take a look at this SO question。
