Android_实现页面跳转（intent的应用）及进阶

实现页面跳转

Intent intent1 = new Intent(Login.this,DataGetActivity.class);//new Intent(currentActivity.this,targetActivity.class);startActivity(intent1);

实现页面跳转，同时获取原先页面信息，传给target页面
ex:
currentActivity里面读取用户名username，在targetActivity里面用

currentActivity:

EditText username = (EditText) findViewById(R.id.username);//获取目标idBundle bundle = new Bundle();bundle.putString("username", username.getText().toString());//将目标id的目标信息以键值对的形式存储Intent intent1 = new Intent(Login.this,DataGetActivity.class);intent1.putExtras(bundle);//传入intentstartActivity(intent1);

targetActivity

        TextView username = (TextView) findViewById(R.id.usernameInfo);        String data = "";        Bundle extras = getIntent().getExtras();        if(extras != null){            data = extras.getString("username");        }        username.setText(data);
