android activity 相互傳值

1，傳一個值的情況：   Main.activity   Pass value：   Intent intent = new Intent(MainActivity.this, SecondActivity.class); intent.putExtra("Main", "123"); startActivityForResult(intent, 0); Get value from other activity @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode == RESULT_OK) { Log.d("debug", "result=" + data.getStringExtra("second")); } super.onActivityResult(requestCode, resultCode, data); }   Test.activity Get value：   Intent intent = getIntent(); final String num = intent.getStringExtra("Main");   Then pass value to main activity Intent intent = new Intent(); intent.putExtra("second", "This is Second Activity's value!"); setResult(RESULT_OK, intent); finish();   如果傳多個值的情況使用 Bundle Pass value： Home Activity： Bundle bundle = new Bundle();   *字符、字符串、布爾、字節數組、浮點數等等，都可以傳*/ bundle.putString("Name", "feng88724"); bundle.putBoolean("Ismale", true);   /*把bundle對象assign給Intent*/ intent.putExtras(bundle);   Get value： Away Activity： /*獲取Intent中的Bundle對象*/ Bundle bundle = this.getIntent().getExtras();   *獲取Bundle中的數據，注意類型和key*/ String name = bundle.getString("Name"); boolean ismale = bundle.getBoolean("Ismale");
