Android : 버튼 너비와 동일한 높이 설정 (테이블 레이아웃 내부)

Question

계산기 용 점토를 만들고자합니다. 이것은 내 MainActivity입니다. 버튼의 너비를 정의하기 위해 가중치를 사용하고 있습니다. 에뮬레이터에서 실행할 때 버튼이 전혀 표시되지 않습니다. 이게 잘 작동하는지 궁금 해서요 (그래서 실수, XML 또는 드로어 블을 검색 할 곳을 알기 위해서)?

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
    setContentView(R.layout.activity_main); 
    setButtonHeight(); 
} 

protected void setButtonHeight() { 
    ArrayList<Button> buttonAL= new ArrayList<Button>(); 

    int id=0; 
    for (int i=0; i<=9; i++){ 
     id= getResources().getIdentifier("b"+i,"id", getPackageName()); 
     buttonAL.add((Button)findViewById(id)); 
    } 

    buttonAL.add((Button)findViewById(R.id.bdiv)); 
    buttonAL.add((Button)findViewById(R.id.bmul)); 
    buttonAL.add((Button)findViewById(R.id.bminus)); 
    buttonAL.add((Button)findViewById(R.id.bplus)); 
    buttonAL.add((Button)findViewById(R.id.bequal)); 
    buttonAL.add((Button)findViewById(R.id.bc)); 
    buttonAL.add((Button)findViewById(R.id.bdot)); 
    buttonAL.add((Button)findViewById(R.id.bop)); 
    buttonAL.add((Button)findViewById(R.id.bcp)); 
    buttonAL.add((Button)findViewById(R.id.bpow)); 
    int size=0; 

    for(Button button: buttonAL) { 
     size = button.getLayoutParams().width; 
     button.setLayoutParams(new TableRow.LayoutParams(size,size)); 
    } 
}

Answer 1

은 그냥 XML로 변경합니다

변경을

<TableRow 
    android:layout_width="0dp" 
    android:layout_height="match_parent" 
    android:weightSum="4"> 

에

<TableRow 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:weightSum="4"> 

weightsum을 할당 할 레이아웃의 너비를 언급해야합니다.

Answer 2

당신은 단순히이 수행 할 수

이

button.getLayoutParams().height = button.getLayoutParams().width; 
button.requestLayout();
