我一直在尝试使用一些编辑文本来实现listview，这些编辑文本在聚焦时选择所有文本。在找到这篇文章之前，没有任何工作：https://stackoverflow.com/questions/24162604/android-edittext-in-listview-with-selection?answertab=active#tab-top。我实现了显示的代码，我遇到了一个小问题。当用户首次打开活动并点击编辑文本时，它将不会选择所有文本，但是如果您点击另一个编辑文本然后点击上一个文本，它将选择文本就好了。有人有什么想法吗？
以下是一些代码：
public class StandSheetCursorAdapter extends CursorAdapter {
private boolean isStartButtonShowing;

private View.OnClickListener minusListener = new View.OnClickListener() {
@Override
public void onClick(View view) {
EditText editText = (EditText) view.getTag(R.id.edit_text_key);
updateEditText(editText, false);
}
};
private View.OnClickListener plusListener = new View.OnClickListener() {
@Override
public void onClick(View view) {
EditText editText = (EditText) view.getTag(R.id.edit_text_key);
updateEditText(editText, true);
}
};
private TextWatcher textWatcher = new TextWatcher() {
public void afterTextChanged(Editable s) {
if(s.length()==1){
selectAllFocusedEditText = null;
}
}
public void beforeTextChanged(CharSequence s, int start, int count, int after){}
public void onTextChanged(CharSequence s, int start, int before, int count){}
};
public StandSheetCursorAdapter(Context context, Cursor cursor, int flags, int standSheetType){
super(context, cursor, flags);
switch (standSheetType){
case 0:
firstColumnKey= InventoryContract.StockItem.CursorColumns.ACTUAL_START_COUNT;

break;
case 1:

答案 0 :(得分：0)
我知道这是延迟的，但我有这个问题好几个星期我想发布适用于我的解决方案，以防任何其他用户偶然发现这个帖子（因为这是我遇到的确切问题）。
进入Android Manifest并在您指定的Activity中添加：
机器人：windowSoftInputMode = “adjustPan”
正如您所提到的，您的EditText没有问题，或者您的EditText在点击时选择所有数据 - 两者都发生了。所以你的问题不是requestFocus（）或setSelectAllOnFocus（）的实现。
当您单击EditText时，ListView将重新调用getView，因为软键盘已重新定义Activity的主窗口以为键盘腾出空间。
通过调用“adjustPan”，您选择不调整Activity的主窗口（第二次调用getView），而是确保无论屏幕上有什么焦点都停留在屏幕上。无论什么焦点都会在必要时平移到屏幕上。
添加这个，希望你会好起来的！同样，这个解决方案适用于那些只有在第二次单击时才能正确选择EditText才能正确选择的人。

迟到的答案，但在我遇到完全相反的问题时可能会帮助其他人：第一次OnFocusChanged调用期间selectAll（）工作，但后续OnFocusChanged调用期间的任何selectAll（）都不会。
我只是将selectAll（）移动到一个runnable处理程序中，如下所示，然后按预期工作！
@Override
public void onFocusChange(final View edit_text_widget, boolean hasFocus)
{
if (hasFocus)
{
new Handler().post(new Runnable()
{
@Override
public void run()
{
edit_text_widget.selectAll();
}
});
}
}
