本文详细阐述了Android应用中用户注册流程，包括输入验证、数据传递和展示过程。通过解析MainActivity和BiaoActivity的代码实现，展示了如何利用Intent进行数据交换，并在BiaoActivity中显示注册信息。

MainActivity.java

public class MainActivity extends Activity implements OnClickListener{
private Button button;
private EditText editText1;
private EditText editText2;
private EditText editText3;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1);
button=(Button) findViewById(R.id.button);
editText1=(EditText) findViewById(R.id.edit_text1);
editText2=(EditText) findViewById(R.id.edit_text2);
editText3=(EditText) findViewById(R.id.edit_text3);
button.setOnClickListener(this);

}

@Override
public void onClick(View v){
switch(v.getId()){
case R.id.button:
// 在此添加逻辑
String inputText1=editText1.getText().toString();
String inputText2=editText2.getText().toString();
String inputText3=editText3.getText().toString();
Intent intent=new Intent(MainActivity.this,BiaoActivity.class);
intent.putExtra("extra_data1", inputText1);
intent.putExtra("extra_data2", inputText2);
intent.putExtra("extra_data3", inputText3);
startActivity(intent);
break;
default:
break;
}
}

}

2.BiaoActivity.java

public class BiaoActivity extends Activity{
private ListView listView;
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.biaoge);
Intent intent1=getIntent();
   String inputText1=intent1.getStringExtra("extra_data1");
   String inputText2=intent1.getStringExtra("extra_data2");
   String inputText3=intent1.getStringExtra("extra_data3");

String[] data={inputText1,inputText2,inputText3};
listView = new ListView(this);
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1,data);
ListView listView=(ListView) findViewById(R.id.list);
listView.setAdapter(adapter);
}
}
