我有一个有苹果、梨和柠檬的东西。我为苹果、梨和柠檬做了单独的布局。
如果选择了任何元素,我想获取该元素的布局。我尝试根据所选布局和inflate()
功能将正确的布局放置到 viewStub 中。inflate()
但是每次定义布局的性能都令人筋疲力尽,有时还会导致错误的工作。
请帮我。
我的一般视图代码:
public class MyView extends RelativeLayout {
private ViewStub viewStub;
private int lemon = 1, apple = 2, pear = 3;
public MyView(Context context) {
this(context, null);
}
public MyView(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
protected void onFinishInflate() {
super.onFinishInflate();
this.viewStub = ViewUtil.findById(this, R.id.view_stub);
}
public void bindElements(int type){
if (type == lemon) {castLemon(); return;}
if (type == apple ) {castApple(); return;}
if (type == pear) {castPear(); return;}
public void castLemon() {
viewStub.setLayoutResource(R.layout.lemon_item);
LemonView lemonView = (LemonView) viewStub.inflate();
}
}
public void castApple() {
viewStub.setLayoutResource(R.layout.apple_item);
AppleView appleView = (AppleView) viewStub.inflate();
}
}
public void castPear() {
viewStub.setLayoutResource(R.layout.pear_item);
PearView pearView = (PearView) viewStub.inflate();
}
}
}
我的一般视图xml:

xmlns:tools="http://schemas.android.com/tools"

</LinearLayout>

柠檬视图.java:
public class LemonView extends FrameLayout {
private ImageView imageView;
public LemonView(Context context) {
this(context, null);
}
public LemonView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public LemonView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
inflate(context, R.layout.lemon_view, this);
imageView = findViewById(R.id.image);
}
