[英]Remove top and bottom black borders from AutoCompleteTextView
[英]PageViewer white borders on top and bottom
我的圖像無法完全適應屏幕。 頂部和底部出現白色邊框我的圖像尺寸為700x1002。
請有人能幫助我獲得這些邊緣並使圖像/容器完全適合屏幕嗎?
layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

android:layout_width="match_parent"
android:layout_height="wrap_content"

<RelativeLayout

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/linearActions"

<com.viewpagerindicator.CirclePageIndicator

app:pageColor="#CCCCCC" />
</RelativeLayout>
</RelativeLayout>
MyAdapter:
public class MyAdapter extends PagerAdapter {
Activity activity;
int imageArray[];
public MyAdapter(Activity act, int[] imgArray) {
imageArray = imgArray;
activity = act;
}
public Object instantiateItem(View collection, int position) {
ImageView view = new ImageView(activity);
view.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT));
view.setScaleType(ScaleType.FIT_CENTER);
view.setImageResource(imageArray[position]);
((ViewPager) collection).addView(view, 0);
return view;
}
@Override
public void destroyItem(View arg0, int arg1, Object arg2) {
((ViewPager) arg0).removeView((View) arg2);
}
@Override
public boolean isViewFromObject(View arg0, Object arg1) {
return arg0 == ((View) arg1);
}
@Override
public int getCount() {
return imageArray.length;
}
@Override
public Parcelable saveState() {
return null;
}
}
嘗試更改您的view.setScaleType(ScaleType.FIT_CENTER);
查看view.setScaleType(ScaleType.CENTER_CROP);
它有點晚了,但是上述解決方案對我都不起作用。 因此,想到了共享我的解決方案的完美方法。 如果在view(ImageView)中設置ScaleType和Params,則LinerLayout / RelativeLayout可能會遇到問題。 因此,只需在viewpagerAdapter布局中像下面一樣設置ImageView的ScaleType即可。
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:src="@drawable/sampleImage"
android:id="@+id/img_pager_item"
android:scaleType="center"
android:clickable="false"
/>
