如何在活動之間傳遞int數組？

Question

我想通過活動之間的高分辨率drawable ints和ImageViews顯示，所以我在第一個活動Examples.class作出這一空白：

private void PATHS(int PATH_1, int PATH_2, int PATH_3, int PATH_4, int PATH_5) 
{ 
    int[] xPATHS = {PATH_1,PATH_2, PATH_3, PATH_4, PATH_5}; 
    Intent intent = new Intent(Examples.this, ExamplesViewer.class); 
    intent.putExtra("PATHS", xPATHS); 
    startActivity(intent); 

} 

而且我把它叫做列表中的聽衆：

list.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
     public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { 

       PATHS(R.drawable.imageone, R.drawable.imagetwo, R.drawable.imagethree, R.drawable.imagefour, R.drawable.imagefive); 
     } 
    }); 
}} 

然後我接受了它的第二個活動 「ExamplesViewer.class」：

Bundle intent = getIntent().getExtras(); 
    int[] PATHS = intent.getIntArray("PATHS"); 
    ImageView xImageView_1 = (ImageView) findViewById(R.id.PATH_1); 
    ImageView xImageView_2 = (ImageView) findViewById(R.id.PATH_2); 
    ImageView xImageView_3 = (ImageView) findViewById(R.id.PATH_3); 
    ImageView xImageView_4 = (ImageView) findViewById(R.id.PATH_4); 
    ImageView xImageView_5 = (ImageView) findViewById(R.id.PATH_5); 


    final BitmapFactory.Options xbm = new BitmapFactory.Options(); 
    xbm.inSampleSize = 2; 

    DisplayMetrics metrics = this.getResources().getDisplayMetrics(); 
    int width = metrics.widthPixels; 
    int height = metrics.heightPixels; 

    Bitmap xImage_1 = BitmapFactory.decodeResource(getResources(), PATHS[0], xbm); 
    xImageView_1.setImageBitmap(xImage_1); 
    xImageView_1.getLayoutParams().height = height; 
    xImageView_1.getLayoutParams().width = width; 
    Bitmap xImage_2 = BitmapFactory.decodeResource(getResources(), PATHS[1], xbm); 
    xImageView_2.setImageBitmap(xImage_2); 
    xImageView_2.getLayoutParams().height = height; 
    xImageView_2.getLayoutParams().width = width; 
    Bitmap xImage_3 = BitmapFactory.decodeResource(getResources(), PATHS[2], xbm); 
    xImageView_3.setImageBitmap(xImage_3); 
    xImageView_3.getLayoutParams().height = height; 
    xImageView_3.getLayoutParams().width = width; 
    Bitmap xImage_4 = BitmapFactory.decodeResource(getResources(), PATHS[3], xbm); 
    xImageView_4.setImageBitmap(xImage_4); 
    xImageView_4.getLayoutParams().height = height; 
    xImageView_4.getLayoutParams().width = width; 
    Bitmap xImage_5 = BitmapFactory.decodeResource(getResources(), PATHS[4], xbm); 
    xImageView_5.setImageBitmap(xImage_5); 
    xImageView_5.getLayoutParams().height = height; 
    xImageView_5.getLayoutParams().width = width; 

的事情是，當我在我的模擬器運行這個它工作正常，但是當我在實際設備上運行它，它帶我到我的MainActivity

PS：我試圖在多個設備上運行，但仍然沒有工作。

Answer 1

這是困擾你：

intent.putExtra("PATHS", xPATHS); 

或者，如果你只是有幾個整數，你可能要輸入路徑整數分別是這樣的：

intent.putExtra("PATH_1", xPATHS[0]); 
intent.putExtra("PATH_2", xPATHS[1]); 
intent.putExtra("PATH_3", xPATHS[2]); 
intent.putExtra("PATH_4", xPATHS[3]); 
intent.putExtra("PATH_5", xPATHS[4]); 

好運。

雖然發送的

int[] xPATHS = {PATH_1,PATH_2, PATH_3, PATH_4, PATH_5}; 
Intent intent = new Intent(Examples.this, ExamplesViewer.class); 
intent.putExtra("PATHS", xPATHS); 

而是嘗試

int[] xPATHS = {PATH_1,PATH_2, PATH_3, PATH_4, PATH_5}; 
Intent intent = new Intent(Examples.this, ExamplesViewer.class); 
Bundle bundle =new Bundle(); 
bundle.putIntArray("PATHS", xPATHS);         // Change here 

而不是

Bundle intent = getIntent().getExtras(); 
int[] PATHS = intent.getIntArray("PATHS"); 

嘗試

Bundle bundle = new Bundle(); 
int[] PATHS = bundle.getIntArrayExtra("PATHS"); // change here
