流程：AppA点击按钮，唤醒AppB并传递参数“hello”。AppB收到“hello”后更新界面，点击AppB上按钮后，唤醒AppA并传递参数“world”。AppA收到“world”后更新界面。
- AppA点击按钮
public void f2(final String data) {
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("com.app.b","org.cocos2dx.cpp.AppActivity"));
intent.putExtra("a2b",data);
startActivity(intent);
}
- AppB接收参数
@Override
protected void onCreate(Bundle savedInstanceState) {
super.setEnableVirtualButton(false);
super.onCreate(savedInstanceState);
getAppData();//接收参数一
}
private void getAppData() {
Intent intent = getIntent();
final String str_a2b = intent.getStringExtra("a2b");
if (str_a2b != null) {
showMsg(str_a2b);
}
}
public void showMsg(final String msg) {
runOnUiThread(new Runnable() {
@Override
public void run() {
android.widget.Toast.makeText(AppActivity.this, msg, Toast.LENGTH_LONG).show();
}
});
}
@Override
protected void onNewIntent(Intent intent) {//接收参数二
super.onNewIntent(intent);
final String str_a2b = intent.getStringExtra("a2b");
if (str_a2b != null) {
showMsg(str_a2b);
}
}
- AppB点击按钮和AppA接收参数跟上面写法类似
