Android 复制粘贴对话框弹出监听实现

来源：互联网发布：everaver renamer mac 编辑：程序博客网时间：2024/06/11 08:26

长按文本框或者webview界面，会弹出复制粘贴剪切等对话框，但是目前好多厂商都是自己写的控件，先说一下对系统的对话框进行监听的情况。

这里是为了监听对话框来对自定义view进行高度的处理，对华为三星等手机做个适配，自定义了一个view，在onLayout方法中根据自定义的view在屏幕中的位置变化来进行判断复制粘贴对话框的弹出和隐藏。代码：

@Overrideprotected void onLayout(boolean changed, int left, int top, int right,int bottom) {super.onLayout(changed, left, top, right, bottom);int[] a = new int[2];getLocationInWindow(a);int currentY = a[1];if (android.os.Build.VERSION.SDK_INT > 18) {int height = getHeight();// TODO 大于0可能会有问题if (currentY > 0 && height != 0) {post(new Runnable() {@Overridepublic void run() {ViewGroup.LayoutParams params = getLayoutParams();params.height = 0;setLayoutParams(params);}});} else if(currentY == 0 && height == 0){post(new Runnable() {@Overridepublic void run() {ViewGroup.LayoutParams params = getLayoutParams();params.height = AppEnv.STATUS_BAR_HEIGHT;setLayoutParams(params);}});}}}

第二种方法，是在activity中进行复制粘贴对话框的弹出和隐藏的回调方法，此方法我本人还未层进行实践，核心代码贴上来日后再做个demo

public void onActionModeStarted(ActionMode mode) {System.out.println("----------onActionModeStarted----------");};@Overridepublic void onActionModeFinished(ActionMode mode) {System.out.println("----------onActionModeFinished----------");super.onActionModeFinished(mode);}

然后就是自定义的实现了，自己写了个小demo，以及文本框和webview自由选择复制这一块有点复杂，还未实现，贴一下自己的demo。

xml就是一个EditText，不贴了，

弹框的xml布局为：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:padding="10dp"    android:background="@android:color/holo_red_light"    android:orientation="horizontal">    <TextView        android:id="@+id/copy"        android:layout_width="0dp"        android:layout_weight="1"        android:gravity="center_horizontal"        android:layout_height="wrap_content"        android:text="复制"/>    <TextView        android:id="@+id/paste"        android:layout_width="0dp"        android:layout_weight="1"        android:gravity="center_horizontal"        android:layout_height="wrap_content"        android:text="粘贴"/>    <TextView        android:id="@+id/cut"        android:layout_width="0dp"        android:layout_weight="1"        android:gravity="center_horizontal"        android:layout_height="wrap_content"        android:text="剪切"/>    <TextView        android:id="@+id/select_all"        android:layout_width="0dp"        android:layout_weight="1"        android:gravity="center_horizontal"        android:layout_height="wrap_content"        android:text="全选"/>    <TextView        android:id="@+id/select"        android:layout_width="0dp"        android:layout_weight="1"        android:gravity="center_horizontal"        android:layout_height="wrap_content"        android:text="选择"/></LinearLayout>

自由选择这块以后再研究了。。。。。。。。。。。。。。。。。。。。。。。。。。
