當添加TextView時，Android應用程序變慢或變爲無響應

Question

我一直在開發這款Android遊戲，並且想知道爲什麼每當我添加此TextView時，我的應用程序開始變得無響應。就像，我的一些按鈕不會按，而其他按鈕，等等。然後，當我從線性佈局中刪除TextView時，一切都恢復正常。請幫忙！

MainActivity

public class MainActivity extends AppCompatActivity { 

boolean started = false; 
boolean place; 
boolean[] tiles = new boolean[60]; 
int prevId = 0; 
int times = 0; 
ArrayList<Integer> IDs = new ArrayList<>(); 

Typeface face; 
TextView num; 

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

    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
      WindowManager.LayoutParams.FLAG_FULLSCREEN); 

    setContentView(R.layout.activity_main); 

    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 

    num = (TextView) findViewById(R.id.count); 

    face = Typeface.createFromAsset(getAssets(),"fonts/ZonaPro-Bold.otf"); 

    num.setTypeface(face); 
} 

public void press(View view) 
{ 
    place = false; 
    int id = view.getId() % 2131427400; 
    String test = "" + id; 

    ImageView img = (ImageView) view; 

    Log.d("TEST", test); 

    *****HERE, I HAVE LOTS OF LOGIC, AND IF-STATEMENTS INCLUDING SOME UNIMPORTANT VARIABLES***** 

    int abs = Math.abs(Math.abs(id - prevId)); 

    if(place && (abs == 1 || abs == 8) && tiles[id] == false && !(img.getTag().toString().equals("bound"))) 
    { 
     img.setImageResource(R.drawable.blue_sphere); 
     tiles[id] = true; 
     prevId = id; 
     times++; 
     IDs.add(id); 
     num.setText("" + times); 
    } 
} 

public void start(View view) 
{ 
    ImageView v = (ImageView) view; 

    if(!started) 
    { 
     started = true; 
     v.setImageResource(R.drawable.blue_sphere); 
     tiles[22] = true; 
     prevId = 22; 
     IDs.add(22); 
     num = (TextView) findViewById(R.id.count); 
     num.setText("0"); 
    } 
} 

public void undo(View view) 
{ 

    for(int ID : IDs) 
    { 
     ImageView re = (ImageView) findViewById(2131427400 + ID); 
     Log.d("TAG", re.getTag().toString()); 

     if(re.getTag().toString().equals("tile")) 
      re.setImageResource(R.drawable.gray_block); 
     else if(re.getTag().toString().equals("start")) 
     { 
      re.setImageResource(R.drawable.start_tile); 
      started = false; 
     } 
     else if(re.getTag().toString().equals("bound")) 
     { 
      re.setImageResource(R.drawable.newer_x); 
     } 
     else if(re.getTag().toString().equals("goal")) 
     { 
      re.setImageResource(R.drawable.new_goal); 
     } 
    } 

    Arrays.fill(tiles, false); 
    times = 0; 
} 
}

我張貼了這麼多的代碼很抱歉，但我有不知道爲什麼會發生這種情況，我希望問題在這些文件中的某處。

Answer 1

問題出在您的start(View view) onClick方法中，您正在引用已在onCreate(Bundle obj)中實例化的TextView，請嘗試刪除它。並將fill_parent替換爲match_parent。

Answer 2

可能低於線

//TextView num; 

首先取消註釋這個問題。

然後不要再聲明如下行（已的onCreate申報）

num = (TextView) findViewById(R.id.count); 

從在onStart（）刪除它。
