Transfer of data between Android interfaces

The transfer of data between different interfaces is a very common operation, and this kind of data is very simple to carry.

This is a simple example, but we passed the first name Zhang San to the second interface.

The accompanying code is as follows:

Main interface:

1  PackageCom.yy.activity.value;2 3 Importandroid.app.Activity;4 Importandroid.content.Intent;5 ImportAndroid.os.Bundle;6 Importandroid.text.TextUtils;7 ImportAndroid.view.View;8 ImportAndroid.widget.EditText;9 ImportAndroid.widget.Toast;Ten  One  Public classMainactivityextendsActivity { A     PrivateEditText Et_name; -  - @Override the     protected voidonCreate (Bundle savedinstancestate) { -         Super. OnCreate (savedinstancestate); - Setcontentview (r.layout.activity_main); -Et_name=(EditText) Findviewbyid (r.id.et_name); +     } -  +      Public voidClick (View view) { A         //get the name entered in the text box atString name=Et_name.gettext (). toString (). Trim (); -         if(Textutils.isempty (name)) { -Toast.maketext ( This, "Please enter your name", Toast.length_long). Show (); -             return; -         } -         //Intentions inIntent intent=NewIntent (); -         //in the same application, so we use explicit intent toIntent.setclassname ( This, "Com.yy.activity.value.ResultActivity"); +         //carry string data, note: Eight basic data types can be carried -Intent.putextra ("name", name); the         //activating the interface * startactivity (intent); $     }Panax Notoginseng}

Result interface:

1  PackageCom.yy.activity.value;2 3 ImportJava.util.Random;4 5 Importandroid.app.Activity;6 ImportAndroid.os.Bundle;7 ImportAndroid.widget.ProgressBar;8 ImportAndroid.widget.TextView;9 Ten  Public classResultactivityextendsActivity { One     PrivateTextView TV_RP; A     PrivateProgressBar PB; - @Override -     protected voidonCreate (Bundle savedinstancestate) { the         Super.

Nextint (101); atTv_rp.settext (name+ ":" +RP); -         //set the progress bar - pb.setprogress (RP); -     } -}
