这里有部分活动屏幕方向改变:
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et = (EditText) findViewById(R.id.editText1);
et.setOnLongClickListener(new View.OnLongClickListener()
{
@Override
public boolean onLongClick(View v)
{
Fragment1 dialogFragment = new Fragment1();
dialogFragment.show(getFragmentManager(), null);
dialogFragment.setTextDialog(et.getText().toString());
return true;
}
});
}
显然,似乎在DialogFragment中出现的对话框应该出现在onLongClick之后的editText上(我知道当屏幕方向改变时Activity重新启动,但它不应该像第一次创建时那样正常启动？ )
我的问题:当我至少打开一次对话框并关闭它时,屏幕方向改变之后我再次在屏幕上显示对话框,就像我长按了editText一样.
我不清楚为什么会这样.
我还附加了对话框片段的结构:
public Dialog onCreateDialog(Bundle savedInstanceState)
{
final Dialog dialog = super.onCreateDialog(savedInstanceState);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
LayoutInflater adbInflater = LayoutInflater.from(getActivity());
View eulaLayout = adbInflater.inflate(R.layout.dialog_crypt, null);
Button btn_OK = (Button) eulaLayout.findViewById(R.id.btnOK);
dialog.setContentView(eulaLayout);
final EditText et = (EditText)eulaLayout.findViewById(R.id.editText2);
et.setText(textDialog);
if(et.length()>0)
{
et.setText(et.getText().toString() + " ");
}
et.setSelection(et.length());
btn_OK.setOnClickListener( …我看到在这个文件中：“dimens.xml”有两个属性：
<dimen name="activity_horizontal_margin">5dp</dimen>
<dimen name="activity_vertical_margin">10dp</dimen>
有没有办法根据使用此文件的屏幕方向自动更改视图的边距？
或者这两个属性就像一个属性一样存在，每次方向更改时我都必须手动检查并将该属性设置为布局边距？？？
提前致谢！
如果我这样查询SELECT column_Name_(example) FROM primarytable WHERE blablabla,调试时会发生异常.
有没有办法指定在某个列中所有的char只是一个字符串？
非常感谢!:)
我写了这段代码:
Sub Insert_Pic_From_File2(PicPath As String, ByVal row As Integer, ByVal col As Integer)
Dim Pic As Picture, Sh As Shape, Rng As Range
Set Rng = Range.Cells(row, col)
Set Rng = Rng.MergeArea
With Rng
Set Sh = ActiveSheet.Shapes.AddPicture(Filename:=PicPath, linkToFile:=msoFalse, SaveWithDocument:=msoTrue, Left:=.Left, Top:=.Top, Width:=.Width, Height:=.Height)
Sh.LockAspectRatio = msoFalse
End With
Set Sh = Nothing
Set Rng = Nothing
End Sub
我从这行说出来:
Insert_Pic_From_File2 ("D:\Area Open\ok.png", y, col_result)
y和col_result都是整数.
当我按下输入程序时出现此错误(意大利语)
errore di compilazione:Previsto:=
我觉得用英语说:
编译错误:需要:=
为什么这个？如果我删除参数y和col_result似乎没有问题,但没有参数.
非常感谢.
