在我的一个活动中,我有三个EditTexts和一个OK按钮. OnFocusChangeListener设置为所有三个EditTexts.每次焦点丢失时,听众都应该触发.
在EditTexts之间切换非常有效.但是,如果用户按下OK按钮,则在按下按钮之前没有针对用户聚焦的EditText触发的焦点改变(失去焦点).
我的代码出了什么问题？
private class MyOnFocusChangeListener implements OnFocusChangeListener {
private EditText editText;
public MyOnFocusChangeListener(final EditText editText) {
super();
this.editText = editText;
}
@Override
public void onFocusChange(final View view,final boolean isFocused) {
if (!isFocused) {
if (editText == editText1) {
// Do a calculation
} else if (editText == editText2) {
// Do another calculation
} else if (editText == editText3) {
// Do a different calculation
}
}
}
}
@Override
public void onCreate(final Bundle bundle) {
// ...
editText1.setOnFocusChangeListener(new MyOnFocusChangeListener(editText1));
editText2.setOnFocusChangeListener(new MyOnFocusChangeListener(editText2));
editText3.setOnFocusChangeListener(new MyOnFocusChangeListener(editText3));
// ...
}
解决方法
当用户点击OK或其他按钮时,您可以尝试清除焦点….
例如
builder.setPositiveButton(android.R.string.ok,new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog,int whichButton)
{
editText1.clearfocus();
editText2.clearfocus();
editText3.clearfocus();
....
}
}
