芬兰湾的科特林的实现。

你可以像这样创建一个简单的函数:

fun dialogYesOrNo(
        activity: Activity,
        title: String,
        message: String,
        listener: DialogInterface.OnClickListener
    ) {
        val builder = AlertDialog.Builder(activity)
        builder.setPositiveButton("Yes", DialogInterface.OnClickListener { dialog, id ->
            dialog.dismiss()
            listener.onClick(dialog, id)
        })
        builder.setNegativeButton("No", null)
        val alert = builder.create()
        alert.setTitle(title)
        alert.setMessage(message)
        alert.show()
    }

像这样叫它:

dialogYesOrNo(
  this,
  "Question",
  "Would you like to eat?",
  DialogInterface.OnClickListener { dialog, id ->
    // do whatever you need to do when user presses "Yes"
  }
})

AlertDialog。Builder真的没有那么难用。一开始肯定有点吓人，但一旦你使用了一点，它就变得简单而强大了。我知道你说过你知道如何使用它，但这里只是一个简单的例子:

DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        switch (which){
        case DialogInterface.BUTTON_POSITIVE:
            //Yes button clicked
            break;

        case DialogInterface.BUTTON_NEGATIVE:
            //No button clicked
            break;
        }
    }
};

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setMessage("Are you sure?").setPositiveButton("Yes", dialogClickListener)
    .setNegativeButton("No", dialogClickListener).show();

你也可以重用那个DialogInterface。OnClickListener如果你有其他是/否框，应该做同样的事情。

如果你是从视图中创建对话框。OnClickListener，你可以使用view.getContext()来获取Context。或者你也可以使用yourFragmentName.getActivity()。

这对我来说很管用:

AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());

    builder.setTitle("Confirm");
    builder.setMessage("Are you sure?");

    builder.setPositiveButton("YES", new DialogInterface.OnClickListener() {

        public void onClick(DialogInterface dialog, int which) {

            // Do nothing, but close the dialog
            dialog.dismiss();
        }
    });

    builder.setNegativeButton("NO", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {

            // Do nothing
            dialog.dismiss();
        }
    });

    AlertDialog alert = builder.create();
    alert.show();

问一个人他是否想打电话对话。

Kotlin在Android::

    override fun onBackPressed() {
        confirmToCancel()
    }

    private fun confirmToCancel() {
        AlertDialog.Builder(this)
            .setTitle("Title")
            .setMessage("Do you want to cancel?")
            .setCancelable(false)
            .setPositiveButton("Yes") {
                dialog: DialogInterface, _: Int ->
                dialog.dismiss()
                // for sending data to previous activity use
                // setResult(response code, data)
                finish()
            }
            .setNegativeButton("No") {
                dialog: DialogInterface, _: Int ->
