setContentView says source not found

问题 I am trying to have a custom GLSurfaceView with some text over it, to display the score in a game. I have made a uniform xml layout based off of someones post here but when I try to load it with a setContentView the app crashes. after debugging I found that it says "Source can not be found". I have rebuilt the R file but that doesn't help. For reference my class that extends GLSurfaceView is called GLView. Any help would be appreciated. package org.kizik.WLTBO; import android.app.Activity;

问题 I am currently working on a custom View which draws some tiles on the canvas. Those tiles are loaded from several files and will be loaded when needed. They will be loaded by an AsyncTask. If they are already loaded they will just be painted on the canvas. This is working properly! If those pictures are loaded the AsyncTask is firing view.postInvalidate() The problem is that my custom View is not firing onDraw(Canvas canvas) everytime I fire view.postInvalidate(). The view.postInvalidate only

使用LinearLayout实现ListView,解决ListView和ScrollView滚动冲突

由 荒凉一梦 提交于 2020-01-24 05:52:34
在项目中，我们常常会遇到一个ScrollView里面会嵌套ListView的情况，但往往你会发现，ListView和ScrollView的滚动时间会有冲突问题，造成ListView不能完全显示。虽然网上有给出解决方案，但事实上并不好用，并不完美。 public void setListViewHeightBasedOnChildren(ListView listView) { // 获取ListView对应的Adapter ListAdapter listAdapter = listView.getAdapter(); if (listAdapter == null) { return; } int totalHeight = 0; for (int i = 0; i < listAdapter.getCount(); i++) { // listAdapter.getCount()返回数据项的数目 View listItem = listAdapter.getView(i, null, listView); listItem.measure(0, 0); // 计算子项View 的宽高 totalHeight += listItem.getMeasuredHeight(); // 统计所有子项的总高度 } ViewGroup.LayoutParams params =

问题 In my android project, I am dynamically adding forms to my linear layout and then destroying them when I am done with a button. However, When I click the "add button" It infinitely adds more forms although I want only one at a time. How can i chec if my linearLayout "accounts" has been added to the view or if it exists in the view at the time? This is the code to add the view. How can I check to see if the view already exists before I add the view? public void showForm(String form){ View view
