INTENTUse Intentto pass data, putExtra()will allow you to put data
意向使用Intent来传递数据，putExtra()将让你把数据
ActivityA
活动A
Intent myIntent = new Intent(ActivityA.this, Activityb.class);
myIntent.putExtra("key", "value");
startActivity(myIntent);
ActivityB
活动B
Intent myIntent = getIntent(); // this is just for example purpose
myIntent.getExtra("key");

try this using Intent:
使用 Intent 试试这个：
In Activity 1 on Button Click:
在按钮单击的活动 1 中：
Intent intent = new Intent(Activityone.class, Activitytwo.class);
intent.putExtra("value2","world");
startActivity(intent);
In Activity 2:
在活动 2 中：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String value1 = super.getIntent().getExtras().getString("value1");
myTextView.setText("value1: " + value1 + ");
}

First Activity -
第一个活动 -
Button btn = (Button)findViewById(R.id.button1);
b.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String passingdata = textview.getText().toString();
Intent i = new Intent(Activity1.this, Activity2.class);
Bundle b = new Bundle();
b.putString("Key", passingdata);
i.putExtras(b);
startActivity(i);
}
});
Second Activity -
第二个活动 -
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.second);
Bundle b = getIntent().getExtras();
String receivingdata = b.getStringExtra("Key");
TextView tv = (TextView)findViewById(R.id.secondtext);
tv.setText(receivingdata);
}

While starting new activity in your button click write below code
在您的按钮中开始新活动时，请单击下面的代码
Intent intent = new Intent();
intent.putExtra("TextValue", text1.getText().toString());
intent.setClass(Activity1.this, Activity2.class);
startActivity(intent);
In your Activity2 in onCreate()
在你的 Activity2 中 onCreate()
String s = getIntent().getStringExtra("TextValue");

You need to put extra parameters on your intent. Watch this article.
您需要根据您的意图添加额外的参数。观看这篇文章。
