如何检测应用程序编辑文本中的粘贴事件?
How to detect the paste event in editext of the application?
如何检测用户何时复制数据并将其粘贴到应用程序的编辑文本中。只需要检测粘贴事件。
例如:当用户从phone中保存的笔记中复制信用卡详细信息并将其粘贴到应用程序相应的edittext中时,我们如何检测到它,只有粘贴事件?
或者是否有其他解决方案可以解决这个问题?
您可以设置监听器Class:
public interface GoEditTextListener {
void onUpdate();
}
为 EditText 创建自我 class:
public class GoEditText extends EditText
{
ArrayList<GoEditTextListener> listeners;
public GoEditText(Context context)
{
super(context);
listeners = new ArrayList<>();
}
public GoEditText(Context context, AttributeSet attrs)
{
super(context, attrs);
listeners = new ArrayList<>();
}
public GoEditText(Context context, AttributeSet attrs, int defStyle)
{
super(context, attrs, defStyle);
listeners = new ArrayList<>();
}
public void addListener(GoEditTextListener listener) {
try {
listeners.add(listener);
} catch (NullPointerException e) {
e.printStackTrace();
}
}
/**
* Here you can catch paste, copy and cut events
*/
@Override
public boolean onTextContextMenuItem(int id) {
boolean consumed = super.onTextContextMenuItem(id);
switch (id){
case android.R.id.cut:
onTextCut();
break;
case android.R.id.paste:
onTextPaste();
break;
case android.R.id.copy:
onTextCopy();
}
return consumed;
}
public void onTextCut(){
}
public void onTextCopy(){
}
/**
* adding listener for Paste for example
*/
public void onTextPaste(){
for (GoEditTextListener listener : listeners) {
listener.onUpdate();
}
}
}
xml:
<com.yourname.project.GoEditText
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/editText1"/>
在你的activity中:
private GoEditText editText1;
editText1 = (GoEditText) findViewById(R.id.editText1);
editText1.addListener(new GoEditTextListener() {
@Override
public void onUpdate() {
//here do what you want when text Pasted
}
});
