在使用EditBox时遇到修改输入内容时每次输入完毕光标就会跳转到最后，经过查询找到大佬给的方案完美解决https://forum.cocos.com/t/1-9-3-editbox/69097，找到安装CocosCreator文件夹修改CocosCreate\CocosCreator\resources\cocos2d-x\cocos\platform\android\java\src\org\cocos2dx\lib路径下Cocos2dxEditBox.java
添加两个私有变量
private int mCurTextLen = 0;
private int mForceCursorPos = 0;
public void setText(String text) {
String newText = updateDomTextCases(text);
super.setText(newText);
this.mCurTextLen = newText.length(); //添加方法
//this.setSelection(newText.length()); //注释原来的方法
}
//新添加方法
public void forceCursorPos(int forcePos) {
this.mForceCursorPos = forcePos;
}
// 新添加方法
public void updateCursorPos() {
int newPos = this.mForceCursorPos < 0 ? 0 : this.mForceCursorPos > this.mCurTextLen ? this.mCurTextLen : this.mForceCursorPos;
this.setSelection(newPos);
this.mForceCursorPos = 0;
}
Cocos2dxEditBoxHelper.java
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
int selectionStart = editBox.getSelectionStart();
int selectionEnd = editBox.getSelectionEnd();
if (selectionStart != selectionEnd || (count > 0 && after > 0)) {
editBox.forceCursorPos(start + after);
} else {
editBox.forceCursorPos(selectionStart - count + after);
}
}
public void afterTextChanged(final Editable s) {
if (!editBox.getChangedTextProgrammatically()) {
editBox.removeTextChangedListener(this);
editBox.setText(editBox.getText().toString());
editBox.updateCursorPos(); // 在这里更新光标位置
editBox.addTextChangedListener(this);
if((Boolean)editBox.getTag()) {
mCocos2dxActivity.runOnGLThread(new Runnable() {
@Override
public void run() {
Cocos2dxEditBoxHelper.__editBoxEditingChanged(index, s.toString());
}
});
}
}
editBox.setChangedTextProgrammatically(false);
}
