代码修改 drawleft 图标大小
Drawable drawable = getResources().getDrawable(int drawableId);
drawable.setBounds(0, 0, width, height);(一定要先设置这个)
radioButton.setCompoundDrawables(null, null, drawable, null);(要使用这个方法设置图片才能生效)
控制EditText不让输入中文(输入内容类型)
自定义EditText重写onCreateInputConnection()方法
在该方法内返回自定义的MyInputConnecttion
@Override
public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
return new MyInputConnecttion(super.onCreateInputConnection(outAttrs),
false);
}
创建MyInputConnecttion继承InputConnectionWrapper实现InputConnection在commitText()方法内部控制不能输入或者可输入的文字类型
class MyInputConnecttion extends InputConnectionWrapper implements InputConnection {
public MyInputConnecttion(InputConnection target, boolean mutable) {
super(target, mutable);
}
/**
* 对输入的内容进行拦截
*/
@Override
public boolean commitText(CharSequence text, int newCursorPosition) {
// 不能输入汉字
if (text.toString().matches("[\u4e00-\u9fa5]+")) {
return false;
}
return super.commitText(text, newCursorPosition);
}
}
让popuwindow的父类上的控件处理Touch事件,不让自处理
public static void setPopupWindowTouchModal(PopupWindow popupWindow,
boolean touchModal) {
if (null == popupWindow) {
return;
}
Method method;
try {
method = PopupWindow.class.getDeclaredMethod("setTouchModal",
boolean.class);
method.setAccessible(true);
method.invoke(popupWindow, touchModal);
} catch (Exception e) {
e.printStackTrace();
}
}
android7.0 popuwindow显示位置错误(全屏置顶)
public void showPopupWindow(PopupWindow popupWindow, View view) {
if (Build.VERSION.SDK_INT < 24) {
popupWindow.showAsDropDown(view);
} else {
int[] location = new int[2];
view.getLocationOnScreen(location);
int y = location[1];
popupWindow.showAtLocation(view, Gravity.NO_GRAVITY, 0, y + view.getHeight());
}
}
