Android:如何在从另一个活动调用时更快地加载一个活动,即使在第二个活动中加载多个内容

我的应用程序中有2个活动,即 Welcome_Activity.java 和 Content_Activity.java

第一个活动工作顺利,但问题出现在 Content_Activity(Second Activity) 从调用 Welcome_Activity(First Activity)

在 onCreate 属于 Second Activity ,我认为内容太多导致活动加载太慢。

例子:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_Puzzle_game);

    q1_tv = (TextView) findViewById(R.id.q1_tv);
    q2_tv = (TextView) findViewById(R.id.q2_tv);
    q3_tv = (TextView) findViewById(R.id.q3_tv);
    q4_tv = (TextView) findViewById(R.id.q4_tv);
    q5_tv = (TextView) findViewById(R.id.q5_tv);
    q6_tv = (TextView) findViewById(R.id.q6_tv);
    q7_tv = (TextView) findViewById(R.id.q7_tv);
    q8_tv = (TextView) findViewById(R.id.q8_tv);
    q9_tv = (TextView) findViewById(R.id.q9_tv);
    q10_tv = (TextView) findViewById(R.id.q10_tv);

    bt1 = (Button) findViewById(R.id.bt1);
    bt2 = (Button) findViewById(R.id.bt2);
    bt3 = (Button) findViewById(R.id.bt3);
    bt4 = (Button) findViewById(R.id.bt4);
    bt5 = (Button) findViewById(R.id.bt5);
    bt6 = (Button) findViewById(R.id.bt6);
    bt7 = (Button) findViewById(R.id.bt7);
    bt8 = (Button) findViewById(R.id.bt8);
    bt9 = (Button) findViewById(R.id.bt9);
    bt10 = (Button) findViewById(R.id.bt10);

    SP = getSharedPreferences("saved_data", MODE_PRIVATE);
    solved = SP.getInt("solved", 0);

    // LoadLevel & ResumeGame is just a method to get data from another class that have array Strings to fill the textviews and buttons 

    if (solved > 0) {
        ResumeGame(null);
    }
    else {
        LoadLevel(null);
    }
}
