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"
  }
})

试试这个:

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

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();

你可以为决策实现一个通用的解决方案，并在另一种情况下使用，而不仅仅是yes/no和自定义警报动画或布局:

像这样的东西;首先创建用于传输数据的类:

public class AlertDecision {

    private String question = "";
    private String strNegative = "";
    private String strPositive = "";

    public AlertDecision question(@NonNull String question) {
        this.question = question;
        return this;
    }

    public AlertDecision ansPositive(@NonNull String strPositive) {
        this.strPositive = strPositive;
        return this;
    }

    public AlertDecision ansNegative(@NonNull String strNegative) {
        this.strNegative = strNegative;
        return this;
    }

    public String getQuestion() {
        return question;
    }

    public String getAnswerNegative() {
        return strNegative;
    }

    public String getAnswerPositive() {
        return strPositive;
    }
}

后的接口，用于返回结果

public interface OnAlertDecisionClickListener {

    /**
     * Interface definition for a callback to be invoked when a view is clicked.
     *
     * @param dialog the dialog that was clicked
     * @param object The object in the position of the view
     */
    void onPositiveDecisionClick(DialogInterface dialog, Object object);
    void onNegativeDecisionClick(DialogInterface dialog, Object object);
}

现在你可以很容易地创建一个utils(在这个类中，你可以为警报实现不同的动画或自定义布局):

public class AlertViewUtils {

    public static void showAlertDecision(Context context,
                                         @NonNull AlertDecision decision,
                                         final OnAlertDecisionClickListener listener,
                                         final Object object) {

        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        builder.setMessage(decision.getQuestion());
        builder.setPositiveButton(decision.getAnswerPositive(),
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        listener.onPositiveDecisionClick(dialog, object);
                    }
                });

        builder.setNegativeButton(decision.getAnswerNegative(),
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        listener.onNegativeDecisionClick(dialog, object);
                    }
                });

        android.support.v7.app.AlertDialog dialog = builder.create();
        dialog.show();
    }
}

最后是活动或片段的召唤;你可以在你的案例或其他任务中使用这个:

public class MainActivity extends AppCompatActivity {

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);
        initResources();
    }

    public void initResources() {
        Button doSomething = (Button) findViewById(R.id.btn);
        doSomething.setOnClickListener(getDecisionListener());
    }

    private View.OnClickListener getDecisionListener() {
        return new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                AlertDecision decision = new AlertDecision()
                        .question("question ...")
                        .ansNegative("negative action...")
                        .ansPositive("positive action... ");
                AlertViewUtils.showAlertDecision(MainActivity.this,
                        decision, getOnDecisionListener(), v);
            }
        };
    }

    private OnAlertDecisionClickListener getOnDecisionListener() {
        return new OnAlertDecisionClickListener() {
            @Override
            public void onPositiveDecisionClick(DialogInterface dialog, Object object) {

                //do something like create, show views, etc...
            }

            @Override
            public void onNegativeDecisionClick(DialogInterface dialog, Object object) {
                //do something like delete, close session, etc ...
            }
        };
    }
} 

AlertDialog.Builder altBx = new AlertDialog.Builder(this);
    altBx.setTitle("My dialog box");
    altBx.setMessage("Welcome, Please Enter your name");
    altBx.setIcon(R.drawable.logo);

    altBx.setPositiveButton("Ok", new DialogInterface.OnClickListener()
    {
      public void onClick(DialogInterface dialog, int which)
      {
          if(edt.getText().toString().length()!=0)
          {
              // Show any message
          }
          else 
          {

          }
      }
    });
    altBx.setNeutralButton("Cancel", new DialogInterface.OnClickListener()
    {
      public void onClick(DialogInterface dialog, int which)
      {
          //show any message
      }

    });
  altBx.show();  

谢谢。我使用API级别2 (Android 1.1)，而不是BUTTON_POSITIVE和BUTTON_NEGATIVE，我必须使用BUTTON1和BUTTON2。
