在扩展RelativeLayout的自定义布局中重写onLayout方法的正确方法是什么? 我试图把所有的意见放在一个表中。这个想法是用ImageView填充一行,直到它满了,然后继续在新行中。扩展自定义布局的Onlayout方法RelativeLayout
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
super.onLayout(changed, l, t, r, b);
int idOfViewToTheLeft = 1;
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(getContext(),);
ImageView bookmark;
for(int counter = 1; counter < getChildCount(); counter++) {
bookmark = (ImageView) findViewById(counter);
if(counter > 1) {
if(this.getWidth() > (bookmark.getLeft() + bookmark.getWidth())) {
params.addRule(RelativeLayout.RIGHT_OF, bookmark.getId() - 1);
} else {
params.addRule(RelativeLayout.BELOW, idOfViewToTheLeft);
idOfViewToTheLeft = bookmark.getId();
}
}
bookmark.setScaleType(ScaleType.CENTER_CROP);
}
}
}
谢谢,该教程示例(代码)真的很有帮助! – lpandzic 2011-02-14 12:59:23
