编辑 :我有一个这样的情况嵌套警报对话框:

public void showMsgDialog(){
        AlertDialog.Builder builder = new AlertDialog.Builder(MapsActivity.this);
        builder.setMessage(MapsActivity.this.getString(R.string.petunjuk_1))
        .setPositiveButton("Lanjut1", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                showMsgDialog1();
                SharedPreferences preferences = getSharedPreferences("MYPREFS", MODE_PRIVATE);
                SharedPreferences.Editor editor = preferences.edit();
                editor.putString("key1", key1);
                editor.apply();
            }
        })
        .setNegativeButton("Tutup", null)
        .create()
        .show();
    }

    public void showMsgDialog1(){
        AlertDialog.Builder builder = new AlertDialog.Builder(MapsActivity.this);
        builder.setMessage(MapsActivity.this.getString(R.string.petunjuk_2))
        .setPositiveButton("Lanjut2", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                showMsgDialog2();
            }
        })
        .setNegativeButton("Tutup", null)
        .create()
        .show();
    }
    public void showMsgDialog2(){
        AlertDialog.Builder builder = new AlertDialog.Builder(MapsActivity.this);
        builder.setMessage(MapsActivity.this.getString(R.string.petunjuk_3))
                .setPositiveButton("Lanjut3", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        showMsgDialog3();
                    }
                })
                .setNegativeButton("Tutup", null)
                .create()
                .show();
    }
    public void showMsgDialog3(){
        AlertDialog.Builder builder = new AlertDialog.Builder(MapsActivity.this);
        builder.setMessage(MapsActivity.this.getString(R.string.petunjuk_4))
                .setPositiveButton("Lanjut4", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        showMsgDialog4();
                    }
                })
                .setNegativeButton("Tutup", null)
                .create()
                .show();
    }
    public void showMsgDialog4(){
        AlertDialog.Builder builder = new AlertDialog.Builder(MapsActivity.this);
        builder.setMessage(MapsActivity.this.getString(R.string.petunjuk_5))
                .setPositiveButton("Lanjut5", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        showMsgDialog5();
                    }
                })
                .setNegativeButton("Tutup", null)
                .create()
                .show();
    }
    public void showMsgDialog5(){
        AlertDialog.Builder builder = new AlertDialog.Builder(MapsActivity.this);
        builder.setMessage(MapsActivity.this.getString(R.string.petunjuk_5))
                .setPositiveButton("Selesai",null)
                .create()
                .show();
    }

编辑 ,然后创建方法:

public void choose(){
        if(key1 == true){
         // go to ShowMsgDialog number you want
        }elseif(key2 == true){
        // go to ShowMsgDialog number you want
        }
    } and so on..

这很好,现在的情况是,如果用户转到另一个活动,并返回到对话框活动,它将再次转到第一个AlertDialog。如何设置上一个AlertDialog setPositiveButton 在最后一次单击每个嵌套的AlertDialog时单击,如果 petunjuk 按钮被单击,它将转到嵌套AlertDialog的最后一次单击,否则它将再次转到第一次AlertDialog。直到最后一个按钮 Selesai 单击按钮。它将永远停留在最后一次单击时。任何人都很感激。谢谢

我们可以用这种格式制作show对话框吗?

int messageIds[] = {R.string.petunjuk_1, R.string.petunjuk_2, ....};
String buttonTexts[] = {"Lanjut1", "Lanjut2", .....};

public void showMsgDialog(final int id){
    AlertDialog.Builder builder = new AlertDialog.Builder(MapsActivity.this);
    builder.setMessage(MapsActivity.this.getString(messageIds[id]))
    .setPositiveButton(buttonTexts[id], new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {

            SharedPreferences preferences = getSharedPreferences("MYPREFS", MODE_PRIVATE);
            SharedPreferences.Editor editor = preferences.edit();
            editor.putString("key", buttonTexts[id]);
            editor.apply();
            if(id < buttonTexts.length() - 1) {
                showMsgDialog(id+1);
            }
        }
    })
    .setNegativeButton("Tutup", null)
    .create()
    .show();
}

调用显示对话框依据

showMsgDialog(0);

**已编辑**

private void onPetunjukButtonClick () {
    SharedPreferences preferences = getSharedPreferences("MYPREFS", MODE_PRIVATE);
    String data = preferences.getString("key", ""); 
    int index = 0;
    if (!data.equals ("")) {
        int i = 0;
        for (String text : dataTexts) {
            if (data.equals (text) {
                index = i;
                break;
            }
            i++;
        }
    }
    showMsgDialog (index);
}
