Activity的跳转与传值

• Activity 跳转 无返回结果

Intent intent = new Intent(AndroidActivityActivity.this, MyActivity.class);
startActivity(intent);

• Activity 跳转 返回结果不带附加数据

请求activity代码 以及响应返回代码

Intent intent = new Intent(AndroidActivityActivity.this, MyActivity.class);
				startActivityForResult(intent, REQUEST_TEST);

protected void onActivityResult(int requestCode, int resultCode,Intent data) {
        if (requestCode == REQUEST_TEST) {
            if (resultCode == RESULT_OK) {
            	//TODO
            }
        }
    }

 处理请求activity代码

MyActivity.this.setResult(RESULT_OK);
MyActivity.this.finish();

•  Activity 跳转 返回结果附加数据

请求activity代码 以及响应返回代码

Intent intent = new Intent(AndroidActivityActivity.this, MyActivity.class);
startActivityForResult(intent, REQUEST_TEST);

protected void onActivityResult(int requestCode, int resultCode,Intent data) {
        if (requestCode == REQUEST_TEST) {
            if (resultCode == RESULT_OK) {
            	Bundle bundle = data.getExtras();
            	Toast.makeText(getApplicationContext(), bundle.getString("phoneNO")
            			+" "+bundle.getString("addr"), Toast.LENGTH_SHORT).show();
            }
        }
    }

  处理请求activity代码

Bundle bundle = new Bundle(); 
bundle.putString("phoneNO", "020-123");
bundle.putString("addr", "china");
MyActivity.this.setResult(RESULT_OK, getIntent().putExtras(bundle));
MyActivity.this.finish();

 ps 数据传输的形式有很多种 看自己怎么封装返回合适就好。
