Answer 1

，你可以在这里获得关于该问题的一些答案：Get/pick an image from Android's built-in Gallery app programmatically

一般情况下，假设你有将图像保存在某个位置，您可以发送一个意图以便通过图库查看它，或者您可以打开文件，读取它，然后将其设置为ImageView。

希望这会有所帮助！

ListView listView; 
int total_data = 11; 

// references to our images 
private Integer[] mThumbIds = { R.drawable.sample_2, R.drawable.sample_3, 
     R.drawable.sample_4, R.drawable.sample_5, R.drawable.sample_6, 
     R.drawable.sample_7, R.drawable.sample_0, R.drawable.sample_1, 
     R.drawable.sample_2, R.drawable.sample_3, R.drawable.sample_4, 
     R.drawable.sample_5, R.drawable.sample_6, R.drawable.sample_7, 
     R.drawable.sample_0, R.drawable.sample_1, R.drawable.sample_2, 
     R.drawable.sample_3, R.drawable.sample_4, R.drawable.sample_5, 
     R.drawable.sample_6, R.drawable.sample_7 }; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    listView = (ListView) findViewById(R.id.listView1); 
    listView.setAdapter(new ImageAdapter()); 

    listView.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, 
       long arg3) { 
      // TODO Auto-generated method stub 

      Bitmap bitmap = BitmapFactory.decodeResource(getResources(), 
        mThumbIds[arg2]); 

      Intent intent = new Intent(StackTestActivity.this, 
        StackTestActivity1.class); 
      intent.putExtra("bitmap", bitmap); 

      startActivity(intent); 

     } 
    }); 
} 

private class ImageAdapter extends BaseAdapter { 

    public ImageAdapter() { 

    } 

    public int getCount() { 
     return mThumbIds.length; 
    } 

    public Object getItem(int position) { 
     return position; 
    } 

    public long getItemId(int position) { 
     return position; 
    } 

    public View getView(int position, View convertView, ViewGroup parent) { 

     View v; 
     if (convertView == null) { 
      LayoutInflater li = getLayoutInflater(); 

      v = li.inflate(R.layout.customview, null); 

     } else { 
      v = convertView; 
     } 

     TextView text = (TextView) v.findViewById(R.id.textView1); 
     text.setText("Image Text"); 

     ImageView icon = (ImageView) v.findViewById(R.id.imageView1); 
     icon.setImageResource(mThumbIds[position]); 

     return v; 
    } 

}

ImageView button; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.second); 

    button=(ImageView)findViewById(R.id.imageView1); 

    Bundle extra=getIntent().getExtras(); 

    if(extra!=null)

     Bitmap bitmap = (Bitmap) getIntent().getParcelableExtra("bitmap"); 
     button.setImageBitmap(bitmap); 
    }
