首页View v = new View(mContext); LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(dp2px(mContext, 29.5f), dp2px(mContext, 31.5f)); v.setLayoutParams(params); v.setBackgroundResource(R.mipmap.manual_touch_point); v.setX((x - dp2px(mContext, 14.75f))); v.setY((y - dp2px(mContext, 15.75f))); frameLayout.addView(v); 为什么阿拉伯语时addView不显示

Android从xml加载到View对象过程解析

Attributeset attrs) {try {String viewClassName = attrs.getAttributeValue(ANDROID_NS_URI, "class");if (viewClassName == null) {viewClassName = name;}else if (name.equals(VIEW_TAG)) {viewClassName = attrs.getAttributeValue(null, "class");if (viewClassName == null) {throw new InflateException(attrs.getPositionDescription()+": <view> tag requires a 'class' attribute");}}Class<?> clazz = null;try {clazz = mContext.getClassLoader().loadClass(viewClassName);if (!View.class.isAssignableFrom(clazz)) {throw new InflateException(attrs.getPositionDescription()+": Class is not a View "+viewClassName);}}catch (ClassNotFoundException e) {throw new InflateException(attrs.getPositionDescription()+": Error inflating class "+viewClassName,e);}Constructor<?> constructor = clazz.getConstructor(MCONSTRUCTOR_SIGNATURE);if (!constructor.isAccessible()) {constructor.setAccessible(true);}Object[] args = new Object[3];args[0] = mContext;args[1] = attrs;args[2] = parent;if (parent != null && !attachToRoot) {args[2] = null;}View view = (View) constructor.newInstance(args);return view;} catch (NoSuchMethodException e) {throw new InflateException(attrs.getPositionDescription()+": Error inflating class "+((viewClassName != null) ? viewClassName : "<unknown>"),e);} catch (IllegalAccessException e) {throw new

可能是因为阿拉伯语是从右向左的书写方向，导致你添加的 View 在屏幕的左侧看不到。你可以尝试将 View 的位置调整到屏幕的右侧，或者在添加 View 前将布局的方向设置为从左向右，即在 Activity 或 Application 的 onCreate() 方法中添加以下代码： ``` getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_LTR); ``` 这样应该可以解决阿拉伯语下 addView 不显示的问题。
