Question

当标记可见时，我正在尝试在FrameLayout中显示TextView。

如下面的代码所示：

                FrameLayout frameLay = new FrameLayout(context);
                FrameLayout.LayoutParams layoutParamsFrame = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.FILL_PARENT, FrameLayout.LayoutParams.FILL_PARENT);

                frameLay.setLayoutParams(layoutParamsFrame);

                TextView theText = new TextView(context);
                theText.setText("text_test");
                theText.setTextColor(Color.WHITE);
                theText.setTypeface(Typeface.DEFAULT_BOLD);

                LayoutParams layoutParamsText = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
                theText.setLayoutParams(layoutParamsText);
                theText.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.BOTTOM);

                first = true;

                frameLay.addView(theText);

这对我不起作用。标记是可见的，我执行此代码，但没有任何反应。我怎样才能解决这个问题？

你可以阅读这个post它解释了如何将TextView添加到FrameLayout

Private Sub cmdClose_Click()
Unload Me
End Sub

Private Sub MonthView1_DateClick(ByVal DateClicked As Date)
On Error Resume Next
Dim xRg As Object
For Each xRg In Selection.Cells
xRg.Value = DateClicked
Next xRg
Unload Me
End Sub

Private Sub UserForm_Initialize()
If IsDate(ActiveCell.Value) Then
Me.MonthView1.Value = ActiveCell.Value
End If
End Sub

所以基本上你必须添加FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, Gravity.CENTER); ((FrameLayout) findViewById(R.id.mainLayout)).addView(mEditText, params);两个参数所以变成了

frameLay.addView（theText，layoutParamsText）;
