在我的應用程序中,當我點擊一個按鈕時,本應移動到新頁面,並顯示圖像。圖像的大小是寬度480像素和高度是1257像素。在橫向模式下圖像非常清晰,在縱向模式下它看起來很舒展。但我需要雙方都完美。如何完美地獲取圖像
的follwing是XML代碼
<?xml version="1.0" encoding="UTF-8"?>
<AbsoluteLayout
android:id="@+id/finalPage"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<ScrollView android:id="@+id/ScrollView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout android:id="@+id/LinearLayout02"
android:layout_width="wrap_content"
android:layout_height="30px"
android:orientation="vertical"
>
<ImageView
android:id="@+id/widget41"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_x="0px"
android:layout_y="0px"
>
</ImageView>
</LinearLayout>>
</ScrollView>>
</AbsoluteLayout>
這是我的源代碼
public class HelpPage extends Activity
{
ImageView BackGroundImage;
int width,height,orientation;
// ImageView help;
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
setContentView(R.layout.help);
height = displaymetrics.heightPixels;
width = displaymetrics.widthPixels;
WebView webview;
webview = (WebView) findViewById(R.id.webview);
// webview.loadUrl("file:///android_asset/helptext.html");
Log.e("FirstImage", "Width = "+width+"Height = "+height+" orientation= "+orientation);
BackGroundImage = (ImageView) findViewById(R.id.widget41);
BackGroundImage.setBackgroundResource(R.drawable.help);
if(width == 320 && height == 480)
{
BackGroundImage.setBackgroundResource(R.drawable.help);
}
//Landscape mode of 320x480
else if(width == 480 && height == 320)
{
BackGroundImage.setBackgroundResource(R.drawable.help);
}
//portrait mode of 480x800
else if(width == 480 && height == 800)
{
BackGroundImage.setBackgroundResource(R.drawable.help);
}
//Landscape mode of 480x800
else if(width == 800 && height == 480)
{
BackGroundImage.setBackgroundResource(R.drawable.help1);
}
//portrait mode of 480x854
else if(width == 480 && height == 854)
{
BackGroundImage.setBackgroundResource(R.drawable.help);
}
//Landscape mode of 480x854
else if(width == 854 && height == 480)
{
BackGroundImage.setBackgroundResource(R.drawable.help1);
}
// help = new ImageView(this);
// help = (ImageView)findViewById(R.id.helps);
}
}
一部分我怎樣才能解決這個問題呢?
