你如何修复(防止它们移动)android中表格布局中单元格的大小?
我在每个单元格内都有一个带有图像按钮的表格布局,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?

您可以使用属性 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" />
这肯定会帮助您完成工作。
谢谢
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、超大)
//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。根据需要在每个 View 中添加 layout_weight
