如何修复（阻止它们移动）android中tablelayout中单元格的大小？

我在每个单元格内都有一个带有图像按钮的tablelayout，问题是，当我更改（或删除）图像时，按钮的大小会发生变化。我该如何防止这种情况？

Answer 1

可以使用属性setMinimum Width / height和Maximum width / height来避免这种情况

<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" />

这肯定会帮助你完成工作。

这可以帮助您以编程方式调整ImageButton，同时检测不同的屏幕尺寸（小，中，大，额外的啤酒）

//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();
        }

将每个View的layout_width设置为0。根据您的需要添加每个View layout_weight
