在动作条图标谨 图片
The actionBar icon should like image
当设备分辨率为1920x1080和android 4.2以上,图标的大小看起来非常小: 图片
When the device resolution is 1920x1080 and android 4.2 above, the icon size looks very small: image
(安卓4.1是正确的)
(android 4.1 is correct)
我的问题似乎是i-want-to-change-actionbar-icon-size.
图标图像尺寸为113x40,然后我用getActionBar()。getHeight()都会获得动作条的高度为56。
The icon image size is 113x40, then I use getActionBar().getHeight() to get ActionBar height is 56.
menu.xml文件:
menu.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/menu_buyer"
android:icon="@drawable/buyer_bts"
android:showAsAction="ifRoom"/>
<item
android:id="@+id/menu_exhibition_bt"
android:icon="@drawable/exhibition_bt"
android:showAsAction="ifRoom"/>
<item
android:id="@+id/menu_oj"
android:icon="@drawable/download_bt"
android:showAsAction="ifRoom"/>
我尝试下面的方法,但不工作:
I tried following method but doesn't work:
创造更大的图标图像(ex.170x60)然后放入绘制,华电国际(xhdpi,xxhdpi ...等)的文件夹
create bigger icon image (ex.170x60) then put into drawable-hdpi(xhdpi, xxhdpi...etc.) folder
使用menu.findItem(R.id.menu_buyer).setIcon(resizeImage(INT渣油,INT W,INT h)条);要调整图标
use menu.findItem(R.id.menu_buyer).setIcon(resizeImage(int resId, int w, int h)); to resize icon
添加一个样式&LT;项目名称=机器人:actionBarSize> 200dp&LT;在style.xml /项目> 在清单文件然后设置主题
added a style < item name="android:actionBarSize" > 200dp < /item > in style.xml then set theme in Manifest file
有没有一种方法可以正确显示的图标?
Is there a way can show the icon correctly?
来不及回答,但是,我找到了答案
Too late to answer but, I found the answer
该方法是相当简单。 1,转换成绘制位图,调整它的大小,并重新转换为可绘制并获得菜单项,并设置图标,新的绘制。
the way was quite simple. 1st, convert drawable into bitmap, resize it and re-convert into drawable and get the item of menu and set the icon as the new drawable.
添加您的活动,这些调整大小的方法,
add your Activity these re-size method,
private Bitmap resizeBitmapImageFn(
Bitmap bmpSource, int maxResolution){
int iWidth = bmpSource.getWidth();
int iHeight = bmpSource.getHeight();
int newWidth = iWidth ;
int newHeight = iHeight ;
float rate = 0.0f;
if(iWidth > iHeight ){
if(maxResolution < iWidth ){
rate = maxResolution / (float) iWidth ;
newHeight = (int) (iHeight * rate);
newWidth = maxResolution;
}
}else{
if(maxResolution < iHeight ){
rate = maxResolution / (float) iHeight ;
newWidth = (int) (iWidth * rate);
newHeight = maxResolution;
}
}
return Bitmap.createScaledBitmap(
bmpSource, newWidth, newHeight, true);
}
和增加工作的onCreateOptionsMenu
and add the work in the onCreateOptionsMenu
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
Bitmap icon = BitmapFactory.decodeResource(getResources(), R.drawable.ic_navigation_drawer); //Converting drawable into bitmap
Bitmap new_icon = resizeBitmapImageFn(icon, 50); //resizing the bitmap
Drawable d = new BitmapDrawable(getResources(),new_icon); //Converting bitmap into drawable
menu.getItem(0).setIcon(d); //choose the item number you want to set
return true;
}
