Passing arguments to intent android

问题

I have the first intent, it starts the second intent. In the second intent, I get the values, and pass the value to the first content and close the second content. How can I do it?

回答1:

You can directly pass parameters to the intent when you create it. If you need to pass objects you need to implement Parcelable interface on the object you pass:

Intent i = new Intent(MyActivity.this, SecondActivity.class);
MyData j = new MyData();
i.putExtra("MyParameter", "Something");
i.putExtra("MyData", j); //only works if MyData implements Parcelable
startActivity(i);

In the second activity you can read your data:

Intent i = getIntent();
Bundle extras = i.getExtras();
if(extras.containsKey("MyParameter")) {
    String something = i.getStringExtra("MyParameter");
}
if(extras.containsKey("MyData")) {
    MyData otherthing = i.getParcelableExtra("MyData");
}

Hope this helps

try this

Passing the parameter to using intent i am passing the message like this

     Intent intent= new Intent(mContext,SuccessActivity.class);

     intent.putExtra("message",mContext.getString(R.string.success_sign_msg));

Get value using intent

     Intent intent=getIntent();
    success_msg_txt.setText(intent.getStringExtra("message"));

try this it helps you
