我想Dialog
用EditText
. 我设想它有两个按钮:一个肯定按钮,它将保留包含在 中的文本EditText
,以及一个否定按钮,它将取消并返回Activity
启动它的按钮,就好像什么都没发生一样。我试过使用AlertDialog
没有成功:
AlertDialog.Builder builder = new Builder(context);
final EditText text = new EditText(context);
builder.setTitle("New Profile").setMessage("Name this new profile").setView(text);
builder.setPositiveButton("Create", new OnClickListener() {
public void onClick(DialogInterface di, int i) {
final String name = text.getText().toString();
//do something with it
}
});
builder.setNegativeButton("Cancel", new OnClickListener() {
public void onClick(DialogInterface di, int i) {
}
});
builder.create().show();
我的setView()
方法有问题吗?使用自定义Dialog
会更实用吗?
编辑:
我得到了几个答案,说代码对他们有用……不知道为什么它对我不起作用。这是日志猫:
