我进行了“活动”,该活动将在单击按钮时弹出。我必须在“图像按钮”上添加侦听器。我已经在XMl中进行了设计,但是我想以编程方式进行设计。
这是我对xml设计的印象。

我必须以编程方式在Java中创建相同的设计。并在“图像按钮”中添加侦听器,以便我可以处理按钮。
答案 0 :(得分:0)
我认为,您提到过AlertDialog 您可以尝试编写此方法:
public void entre () {
AlertDialog.Builder alert = new AlertDialog.Builder(MainActivity.this);
alert.setTitle("Something");
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//what you need to do after click "OK"
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//what you need to do after click "Cancel"
}
});
alert.show();
}
并将其添加到onClickListner中:
public void onButtonClick(View view) {
entre ();
}
您将获得标题为“ Something”的弹出窗口,并带有两个按钮:“ Ok”和“ Cancel”
