如何将评级值中的评级值传递给另一个活动中的AlertDialog [英] How do I pass a rating value from a Ratingbar to an AlertDialog in another activity

问题描述

这是我在DetailActivity中的意图代码。 DetailActivity拥有五星级的ratingBar。



public void finish（）{

Intent intent = new Intent（）;

Toast.makeText（NewsDetailActivity.this，

评分栏点击，

Toast.LENGTH_LONG）。show（）;

intent.putExtra（title，title）;

intent.putExtra（rating，rating）;

setResult（RESULT_OK，intent ）;

super.finish（）;



这是我的mainActivity中的代码。目标是让用户选择要评分的星星。当后退按钮被推到前一个屏幕（即mainActivity）时，警报将提示在detailActivity中选择的金额/值。



protected void onActivityResult（int requestCode ，int resultCode，Intent data）{

super.onActivityResult（requestCode，resultCode，data）;

Log.i（TAG，onActivityResult）;



if（resultCode == RESULT_OK）{

if（data.hasExtra（title）&& data.hasExtra（rating））{

String title = data.getExtras（）。getString（title）;

float action = data.getExtras（）。getFloat（rating）;



Toast.makeText（MainActivity.this，Lets Go，Toast.LENGTH_LONG）。show（）;



AlertDialog alertDialog = new AlertDialog.Builder（this）.create（）;

alertDialog.setTitle（这是文章评级）;

alertDialog.setMessage（评分是多少个星星）;

alertDialog.setButton（OK，new DialogInterface.OnClickListener（）{

public void onClick（DialogInterface dialog，int id）{

dialog.dismiss（）;



}

}）;

alertDialog.show（）;

This is my intent code that is in my DetailActivity. The DetailActivity host the ratingBar with five stars.

public void finish() {
Intent intent = new Intent();
Toast.makeText(NewsDetailActivity.this,
"Rating Bar Clicked",
Toast.LENGTH_LONG).show();
intent.putExtra("title", title);
intent.putExtra("rating", "rating");
setResult(RESULT_OK, intent);
super.finish();

This is the code that is in my mainActivity. The goal is for the user to select the stars to rate. When the back button is pushed to the previous screen which is the mainActivity the alert will prompt amount/value that was selected in the detailActivity.

protected void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
Log.i(TAG,"onActivityResult");

if (resultCode == RESULT_OK ) {
if (data.hasExtra("title") && data.hasExtra("rating")) {
String title = data.getExtras().getString("title");
float action = data.getExtras().getFloat("rating");

Toast.makeText(MainActivity.this, "Lets Go", Toast.LENGTH_LONG).show();

AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("This is the article rating");
alertDialog.setMessage("rating is how many stars");
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();

}
});
alertDialog.show();
