我正在开发一个 Android 应用程序.在我的应用程序中,我必须使用基于文本的图像.所以我为 EditText
编写 OnChangeListener()
.以下是我的示例代码.
I am working on an Android application.In my app I have to use images based on the text.So I write OnChangeListener()
for EditText
.The following is my sample code.
edt.addTextChangedListener(this);
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
CharSequence cs=convert(edt.getText.toString());
edt.setText(cs);
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
}
但我收到上述代码的异常.我知道异常的原因是从 afterTextChanged()
方法调用 setText()
.但是我必须根据相同的 EditText
文本更改来更改 EditText
文本值.帮助我的朋友
But I am getting Exception for the above code.I know the reason for the exception is calling setText()
from afterTextChanged()
method. But I have to change the EditText
text value based on the same EditText
text change.Help me friends
只需在设置文本之前移除您的监听器,并在完成后重新注册,如下所述:
Just simply remove your listener before you set the text, and register it again after you are done, like described here:
添加 onTextChanged 实现后清除 EditText 文本
