WindowManagerImpl类,WindowManagerImpl的路径：android.view.WindowManagerImpl @Override public void addView...view, @NonNull ViewGroup.LayoutParams params) { applyDefaultToken(params); mGlobal.addView...mGlobal.removeView(view, false); } WindowManagerImpl并没有直接实现Window的三大操作，而是全部交给了WindowManagerGlobal: public void addView

LayoutParams基本用法 TextView textView1 = new TextView(this); textView1.setText("TextView1"); linearLayout.addView...setText("TextView3"); textView3.setLayoutParams(new LinearLayout.LayoutParams(100, 100)); linearLayout.addView...a.getDimensionPixelSize( R.styleable.ViewGroup_MarginLayout_layout_marginVertical, -1); ... } ... } } addView...流程 public void addView(View child) { addView(child, -1); } public void addView(View child, int index...(View child, int index, LayoutParams params) { if (DBG) { System.out.println(this + " addView");

比如:view.AddView(...). 4.在追加的父控件内时，可以指定布局的方式。 在动态添加完毕后，我们还需要能够获得对这些动态添加后的控件的值。...LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT); row.addView...(txtView1); row.addView(edit1); LayoutParams layoutParams2 = new LayoutParams...(ViewGroup.LayoutParams.FILL_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT); _pnlContent.addView...(editText); row.addView(btnRemove); tablleLayout.addView(row,layoutParams2); 全文完，代码下载
上一篇 Flutter混合开发：Android接入Flutter 我们讲到在 Flutter混合开发 中主要有、有 addView （页面局部Flutter） 和 setContentView （整个页面...addView public class MainActivity extends AppCompatActivity { @Override protected void onCreate...(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT); frameLayout.addView...frameLayout.setVisibility(View.VISIBLE); flutterView.addFirstFrameListener(listeners); frameLayout.addView...FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT); getWindow().getDecorView().post(() -> frameLayout.addView
PriceBoardAdapter priceBoardAdapter = new PriceBoardAdapter(context); listView.setAdapter(priceBoardAdapter); addView...linearLayout = new LinearLayout(getContext()); linearLayout.setOrientation(VERTICAL); linearLayout.addView...(nameView,p); linearLayout.addView(enCodeView,p); addView(linearLayout, p); p = new LinearLayout.LayoutParams...linearLayout = new LinearLayout(getContext()); linearLayout.setOrientation(VERTICAL); linearLayout.addView...(priceView,p); addView(linearLayout, p); } public void setItem(PriceData data){ priceData = data;
(textView3) 我们看看 addView() 都做了什么。...public void addView(View child) { addView(child, -1); } public void addView(View child, int index)...(View child, int index, LayoutParams params) { if (DBG) { System.out.println(this + " addView");...甚至是我们即使在 addView() 之前设置了错误的 LayoutParams 值，系统也会我们帮我们进行纠正。...虽然系统已经做的足够完善，帮我们各种矫正错误，但在 addView() 之后，我们还强行设置错误的 LayoutParams，那还是一定会报 ClassCastException 的。

在注释2处调用了WindowManager的addView方法，addView方法定义在WindowManager的父类接口ViewManager中，而实现addView方法的则是WindowManagerImpl...在WindowManagerImpl的addView方法中，接着会调用WindowManagerGlobal的addView方法： frameworks/base/core/java/android/view...在注释2处得到ViewManager类型的wm对象，在注释3处调用了wm的addView方法，而addView方法的实现则是在WindowManagerImpl中，此后的过程在上面的系统窗口的添加过程已经讲过...，唯一需要注意的是addView的第一个参数是DecorView。...结语 ViewManager不只定义了addView方法用来添加窗口，还定义了updateViewLayout和removeView方法用来更新和删除窗口，如下所示。 ?
mLeftParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, TRUE); // 添加到 ViewGroup addView...LayoutParams.MATCH_PARENT); mRightParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, TRUE); addView...LayoutParams.MATCH_PARENT); mTitlepParams.addRule(RelativeLayout.CENTER_IN_PARENT, TRUE); addView...mLeftParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, TRUE); // 添加到 ViewGroup addView...mLeftParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, TRUE); // 添加到 ViewGroup addView
实例化View后，一般还会调用addView方法将View对象添加到指定的ViewGroup中。...ViewGroup实现了以下五种addView方法的重载版本： /** * 重载方法1：添加一个子View * 如果这个子View还没有LayoutParams，就为子View设置当前ViewGroup...默认的LayoutParams */ public void addView(View child) { addView(child, -1); } /** * 重载方法2：在指定位置添加一个子View...(child, -1, params); } /** * 重载方法4：添加一个子View，并使用传入的LayoutParams */ @Override public void addView(View...的前四个重载方法最终都会调用第五个重载版本，即addView(View child, int index, LayoutParams params)。

(textView, lp2); 上面代码展示的是3种往LinearLayout里动态添加TextView的方式，其中都涉及到了addView这个方法。...我们来看看addView的几个重载方法： //这3个方法都来自于基类ViewGroup public void addView(View child) { addView(child...(child, index, params); } public void addView(View child, LayoutParams params) { addView...(child, -1, params); } 可以看出addView(View child)是调用了addView(View child, int index)方法的，在这个里面对child...（果然还是勤劳致富呀…） 上面三个重载的addView方法最终都调用了addView(View child, int index, LayoutParams params)这个参数最多的方法: public
一、说明 添加视图文件的时候有两种方式：1、通过在xml文件定义layout；2、java代码编写 二、前言说明 1.构造xml文件 2.LayoutInflater 提到addview，首先要了解一下...savedInstanceState); setContentView(R.layout.activity_dynamic); mContext=this; initView(); mLl_parent.addView...(addView1()); mLl_parent.addView(addView2()); } private void initView() { // TODO 初始化视图 mLl_parent=(LinearLayout...StatedButton) findViewById(R.id.sbtn_navback); mSbtn_back.setOnClickListener(this); } private View addView1...tv1.setText("姓名:"); tv2.setText("李四"); tv2.setPadding(calculateDpToPx(50), 0, 0, 0);//设置边距 view.addView
