如何从一个活动将值传递给另一个机器人？ [英] How to pass a value from one Activity to another in Android?

问题描述

我创建了一个带有AutuCompleteTextView [ACTV]和按钮的活动。我进入了ACTV一些文本，然后$​​ P $ PSS的按钮。 之后我preSS的按钮，我想活动到另一个活动。在第二个活动我只是想显示为一个TextView在ACTV进入（第一actvity的）文本。

I have created an Activity with a AutuCompleteTextView[ACTV] and button. I enter some text in the ACTV then press the button. After I press the button I want the Activity to go to another Activity. In the second Activity I just want to display the text entered in ACTV(of the first actvity) as a TextView.

我知道如何启动第二个活动是如下：

I know how to start the second activity which is as below:

Intent i = new Intent(this, ActivityTwo.class);
startActivity(i);

我有codeD此获得来自ACTV输入的文本。

I have coded this to obtain the text entered from the ACTV.

AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete);
CharSequence getrec=textView.getText();

在这里我的问题是如何通过getrec（后I $ PSS的按钮p $）从第一个活动到第二。后来又免费获赠getrec中的第二个活动。

My question here is how to pass "getrec" (after I press the button) from the first Activity to the second. And later recieve "getrec" in the second activity.

请假设通过使用我所创建的事件处理程序类按钮的onClick（视图v）

Please assume that I have created the event handler class for the button by using "onClick(View v)"

推荐答案

您可以使用捆绑在Android的做同样的

You can use Bundle to do the same in Android

创建的意图：

Intent i = new Intent(this, ActivityTwo.class);
AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete);
String getrec=textView.getText().toString();

//Create the bundle
Bundle bundle = new Bundle();

//Add your data to bundle
bundle.putString("stuff", getrec);

//Add the bundle to the intent
i.putExtras(bundle);

//Fire that second activity
startActivity(i);

现在你的第二个活动从包中检索数据：

Now in your second activity retrieve your data from the bundle:

//Get the bundle
Bundle bundle = getIntent().getExtras();

//Extract the data…
String stuff = bundle.getString("stuff");
