Question

按下对话框的按钮时，我试图打开一个对话框。 - ＆GT; buttonPressed - ＆gt; Dialog1 - ＆gt; Dialog2

创建第一个对话框如下：

(When button is pressed):

final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.dialog1);         //<-- dialog1 contains a button
final Button button1 = (Button)dialog.findViewById(R.id.button1);  //<--in dialog1

button1.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        //A NEW DIALOG BOX SHOULD APPEAR HERE WHEN BUTTON1 GETS CLICKED
    }
});

dialog.show();

到目前为止，这是我的代码。我试过的是关闭对话框，然后打开一个新的对话框：

dialog.dismiss();
Dialog dialog2 = new Dialog(context);
dialog2.setContentView(R.layout.dialog2);

dialog.show();

但是当试图打开一个像这样的新对话框时，我在Coreographer.class中遇到了一些错误。我假设这是因为关闭的对话框无法创建新的对话框。现在我的问题是，如何通过点击它的按钮从另一个对话框中打开一个对话框？

Answer 1

在按钮上单击对话框

时尝试此操作

Dialog dialog2 = new Dialog(context);
dialog2.setContentView(R.layout.dialog2);
dialog.dismiss();
dialog2.show();

Answer 2

而不是使用上下文

Dialog dialog2 = new Dialog(YourActivityName.this);

Answer 3

试试

final Dialog dialog1 = new Dialog(context);
dialog.setContentView(R.layout.dialog1);         //<-- dialog1 contains a button
final Button button1 = (Button)dialog1.findViewById(R.id.button1);  //<--in dialog1

button1.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        //A NEW DIALOG BOX SHOULD APPEAR HERE WHEN BUTTON1 GETS CLICKED
     Dialog dialog2 = new Dialog(context);
     dialog2.setContentView(R.layout.dialog2);
     dialog1.dismiss();
     dialog2.show();
    }
});

dialog.show();
