AlertDialog按钮不显示第二个屏幕的正确消息

Question

我遇到了一个问题，其中AlertDialog按钮没有显示第二个屏幕的正确消息。

预期结果：第一个屏幕在AlertDialog和。中显示消息AAAAAAAAAAA                  第二个屏幕应显示差异消息“CCCCCCC”

问题：对于第二个屏幕，它显示与第一个屏幕相同的消息，即使消息已在java类中更改。

以下是我的Tuto2Activity.java

public class Tuto2Activity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tuto2);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

    }

    public void open(View view){
        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
        alertDialogBuilder.setTitle("How to Use");
        alertDialogBuilder.setMessage("Provide a description about One BAJA in term of how to use it and benefits using it");
        alertDialogBuilder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                dialog.dismiss();
                            }
                        });


        AlertDialog alertDialog = alertDialogBuilder.create();
        alertDialog.show();
    }


    public void onRadioButtonClicked(View view) {

          boolean checked = ( (RadioButton) view). isChecked();

           switch (view.getId()) {
               case R.id.radioButton1:
                   if (checked)
                       setContentView(R.layout.activity_tuto2);
                      break;
               case R.id.radioButton2:
                   if (checked)
                       setContentView(R.layout.activity_tuto3);
                   break;
               case R.id.radioButton3:
                   if (checked)
                       setContentView(R.layout.activity_tuto4);
                   break;
               case R.id.radioButton4:
                   if (checked)
                       setContentView(R.layout.activity_tuto5);
                   break;
               case R.id.radioButton5:
                   if (checked)
                       setContentView(R.layout.activity_tuto6);

           }

    }

}

Tuto3Activity.java：

     public class Tuto3Activity extends AppCompatActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tuto3);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
    }


    public void open(View view){
        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(Tuto3Activity.this);
        alertDialogBuilder.setTitle("How to Use");
        alertDialogBuilder.setMessage("Show the list type of vegetables and flowers and information care");
        alertDialogBuilder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface arg1, int arg2) {
            }
        });

        alertDialogBuilder.setNegativeButton("No",new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                finish();
            }
        });

        AlertDialog alertDialog = alertDialogBuilder.create();
        alertDialog.show();
    }





public void onRadioButtonClicked(View view) {

        boolean checked = ( (RadioButton) view). isChecked();

        switch (view.getId()) {
            case R.id.radioButton1:
                if (checked)
                    setContentView(R.layout.activity_tuto2);
                break;
            case R.id.radioButton2:
                if (checked)
                    setContentView(R.layout.activity_tuto3);
                break;
            case R.id.radioButton3:
                if (checked)
                    setContentView(R.layout.activity_tuto4);
                break;
            case R.id.radioButton4:
                if (checked)
                    setContentView(R.layout.activity_tuto5);
                break;
            case R.id.radioButton5:
                if (checked)
                    setContentView(R.layout.activity_tuto6);

        }

    }


}

您可以尝试使用onClickListener而不是onClick（在xml中）。

    Button myButton = (Button)findViewById(R.id.myButtonID);
    myButton .setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            //Alert dialog codes...
        }
    });
