Activity通过bundle传递数据
作者:互联网
从AActivity.java向BActivity.java传递数据:
建立AActivity.java文件建立bundle:
1 public class AActivity extends AppCompatActivity { 2 private Button btnJump; 3 @Override 4 protected void onCreate(Bundle savedInstanceState) { 5 super.onCreate(savedInstanceState); 6 setContentView(R.layout.activity_aactivity); 7 btnJump=findViewById(R.id.jump); 8 btnJump.setOnClickListener(new View.OnClickListener() { 9 @Override 10 public void onClick(View view) { 11 //数据传递 12 Intent intent=new Intent(AActivity.this,BActivity.class); 13 Bundle bundle=new Bundle(); 14 bundle.putString("name","霉霉"); 15 bundle.putInt("age",30); 16 intent.putExtras(bundle); 17 startActivity(intent); 18 19 } 20 }); 21 } 22 }
在BActivity.java文件中接收bundle:
1 public class BActivity extends AppCompatActivity { 2 private TextView TVtitle2; 3 @Override 4 protected void onCreate(Bundle savedInstanceState) { 5 super.onCreate(savedInstanceState); 6 setContentView(R.layout.activity_bactivity); 7 TVtitle2=findViewById(R.id.tv_title2); 8 9 Bundle bundle=getIntent().getExtras(); 10 String name=bundle.getString("name"); 11 int age=bundle.getInt("age");//传递数据 12 13 TVtitle2.setText(name+":"+age); 14 } 15 }
