如何修復Android中桌面佈局中單元格的大小android

Question

如何修復（防止它們移動）android中tablelayout中單元格的大小？

我在每個單元格內都有一個帶有圖像按鈕的tablelayout，問題是，當我更改（或刪除）圖像時，按鈕的大小會發生變化。我如何防止這種情況？

Answer 1

有物業setMinimum寬度/高度和最大寬度/高度，你可以使用以避免這種情況

<ImageButton 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:minWidth="100dp" 
    android:maxWidth="200dp" 
    android:minHeight="100dp" 
    android:maxHeight="200dp" 
    android:src="@drawable/ic_launcher" /> 

這一定會幫助您完成工作。

這可以幫助您與檢測不同的屏幕尺寸（小，medim，超大，啤酒）一起編程調整你的ImageButton

//Determine screen size 
    if ((getResources().getConfiguration().screenLayout &  Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_LARGE) {  
     Toast.makeText(this, "Large screen",Toast.LENGTH_LONG).show(); 

    } 
    else if ((getResources().getConfiguration().screenLayout &  Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_NORMAL) {  
     Toast.makeText(this, "Normal sized screen" , Toast.LENGTH_LONG).show(); 

    } 
    else if ((getResources().getConfiguration().screenLayout &  Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_SMALL) {  
     Toast.makeText(this, "Small sized screen" , Toast.LENGTH_LONG).show(); 
    } 
    else { 
     Toast.makeText(this, "Screen size is neither large, normal or small" , Toast.LENGTH_LONG).show(); 
    } 




    //Determine density 
    DisplayMetrics metrics = new DisplayMetrics(); 
     getWindowManager().getDefaultDisplay().getMetrics(metrics); 
     int density = metrics.densityDpi; 

     if (density==DisplayMetrics.DENSITY_HIGH) { 
      Toast.makeText(this, "DENSITY_HIGH... Density is " + String.valueOf(density), Toast.LENGTH_LONG).show(); 
     } 
     else if (density==DisplayMetrics.DENSITY_MEDIUM) { 
      Toast.makeText(this, "DENSITY_MEDIUM... Density is " + String.valueOf(density), Toast.LENGTH_LONG).show(); 
     } 
     else if (density==DisplayMetrics.DENSITY_LOW) { 
      Toast.makeText(this, "DENSITY_LOW... Density is " + String.valueOf(density), Toast.LENGTH_LONG).show(); 
     } 
     else { 
      Toast.makeText(this, "Density is neither HIGH, MEDIUM OR LOW. Density is " + String.valueOf(density), Toast.LENGTH_LONG).show(); 
     }

設置每個視圖的layout_width等於0 添加在每個View layout_weight，根據您的需要
