将MainActivity页面的数据：姓名、年龄、性别，传递给新的Activity页面显示出来
- MainActivity.java页面
package com.example.dell.activity;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.TextUtils;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
/*注意：这里的button和textView2是在xml里button和TextView的id名称,根据自己的id来定义*/
private Button button;
private TextView textView2;
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.button);
textView2=(TextView) findViewById(R.id.textView2);
button.setOnClickListener(new View.OnClickListener(){
public void onClick(View v){
//String text =textView2.getText().toString();
String name=textView2.getText().toString();
Intent intent =new Intent(MainActivity.this,OpenActivity.class);
// intent.setClassName(MainActivity.this,"OpenActivity.class");
intent.putExtra("name","姓名：gongjuan");
intent.putExtra("age","年龄：20");
intent.putExtra("sex","性别：女");
startActivity(intent);
startActivityForResult(intent,1);
}
});
}
protected void onActivityResukt(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1) {
if (resultCode == 1) {
String string = data.getStringExtra("extra_data");
}
}
}
}
- 在新activity页面
package com.example.dell.activity;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
public class OpenActivity extends AppCompatActivity {
private TextView textView1;
private TextView textView5;
private TextView textView6;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_open);
textView1= (TextView) findViewById(R.id.textView1);
textView5= (TextView) findViewById(R.id.textView5);
textView6=(TextView) findViewById(R.id.textView6);
Intent intent = new Intent();
String name=getIntent().getStringExtra("name");
String age=getIntent().getStringExtra("age");
String sex=getIntent().getStringExtra("sex");
textView1.setText(name);
textView5.setText(age);
textView6.setText(sex);
setResult(1,intent);
}
}
布局就不发了
