Android EditText禁止复制粘贴
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
1,自定義EditText
package com.example.ui;
import android.annotation.SuppressLint;
import android.content.Context;
import android.util.AttributeSet;
import android.view.ActionMode;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.EditText;@SuppressLint("NewApi")
public class NoMenuEditText extends EditText {
private final Context context;/**
* This is a replacement method for the base TextView class' method of the
* same name. This method is used in hidden class android.widget.Editor to
* determine whether the PASTE/REPLACE popup appears when triggered from the
* text insertion handle. Returning false forces this window to never
* appear.
*
* @return false
*/
boolean canPaste() {
return false;
}/**
* This is a replacement method for the base TextView class' method of the
* same name. This method is used in hidden class android.widget.Editor to
* determine whether the PASTE/REPLACE popup appears when triggered from the
* text insertion handle. Returning false forces this window to never
* appear.
*
* @return false
*/
@Override
public boolean isSuggestionsEnabled() {
return false;
}public NoMenuEditText(Context context) {
super(context);
this.context = context;
init();
}public NoMenuEditText(Context context, AttributeSet attrs) {
super(context, attrs);
this.context = context;
init();
}public NoMenuEditText(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
this.context = context;
init();
}private void init() {
this.setCustomSelectionActionModeCallback(new ActionModeCallbackInterceptor());
this.setLongClickable(false);
}/**
* Prevents the action bar (top horizontal bar with cut, copy, paste, etc.)
* from appearing by intercepting the callback that would cause it to be
* created, and returning false.
*/
private class ActionModeCallbackInterceptor implements ActionMode.Callback {
private final String TAG = NoMenuEditText.class.getSimpleName();public boolean onCreateActionMode(ActionMode mode, Menu menu) {
return false;
}public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;
}public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
return false;
}public void onDestroyActionMode(ActionMode mode) {
}
}
}
2,在layout.xml文件中這樣使用
<com.example.ui.NoMenuEditText
android:id="@+id/ddd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="禁止復制粘貼" />
?
