如何在android中将动态图像设置为ViewFlipper？

Question

我正在做这些正在加载静态这些图像？

public class ArchiveGroup extends Activity  {
    Button btn;
    ViewFlipper flip;
    public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.next);
                btn=(Button)findViewById(R.id.btn);
                flip=(ViewFlipper)findViewById(R.id.flip);

        }
            public void ClickHandler(View v)
            {
             flip.showNext();
            }
            public void ClickHandler1(View v)
            {
            Toast.makeText(this,"text",Toast.LENGTH_LONG).show();
            }
}

我在ViewFlipper xml文件中使用了三个imageview

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
    <Button
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Flip"
    android:id="@+id/btn"
    android:onClick="ClickHandler"
    />
    <ViewFlipper
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:id="@+id/flip"
    >
    <ImageView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:src="@drawable/ic_launcher"
    />
     <ImageView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:src="@drawable/ic_launcher"
    />
    <ImageView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:src="@drawable/ic_launcher"
    />

    </ViewFlipper>
</LinearLayout>

如何将动态图像设置为这些imageView.通过使用单个ImageView.

Answer 1

在你的xml中只添加这个,

<ViewFlipper android:id="@+id/flipper" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content"> 
</ViewFlipper>

不需要包含任何ImageViews.

现在在编码中执行此操作.

考虑到您已将图像存储在这样的数组中,

int gallery_grid_Images[]={R.drawable.gallery_image_1,R.drawable.gallery_image_2,R.drawable.gallery_image_3,
        R.drawable.gallery_image_4,R.drawable.gallery_image_5,R.drawable.gallery_image_6,R.drawable.gallery_image_7,
        R.drawable.gallery_image_8,R.drawable.gallery_image_9,R.drawable.gallery_image_10
        };

现在在你的onCreate()中,

viewFlipper = (ViewFlipper) findViewById(R.id.flipper);
 for(int i=0;i<gallery_grid_Images.length;i++)
        {
        //  This will create dynamic image view and add them to ViewFlipper
            setFlipperImage(gallery_grid_Images[i]);
        }

现在将此方法添加到您的活动中,

private void setFlipperImage(int res) {
    Log.i("Set Filpper Called", res+"");
    ImageView image = new ImageView(getApplicationContext());
    image.setBackgroundResource(res);
    viewFlipper.addView(image);
}

而已.而现在使用viewFlipper.showNext(); 和 viewFlipper.showPrevious(); 方法,您可以显示动态图像.
