我目前正在使用表格布局,并以编程方式添加行和按钮。但是,当我添加视图时,它们中的许多将不在屏幕上。有没有办法以编程方式将尺寸设置为屏幕的一部分。
我在Android方面有不错的经验,但对Kotlin还是陌生的。
这是我添加视图的地方
private fun setupTable () {
for(i in 0 until this.rowSize) {
val row = TableRow(context)
row.layoutParams
row.layoutParams = ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT)
for(j in 0 until this.columnSize) {
val button = Button(context)
button.apply {
layoutParams = TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT)
text = "R $i C $j"
}
row.addView(button)
}
wordLayout?.addView(row)
}
}
这里是图片供参考。在这里,我想要一个10x10的桌子,并适合TableLayout中的所有按钮。
答案 0 :(得分:0)
尝试以下代码:
package net.androidly.androidlylayouts
class MainActivity : AppCompatActivity() {
val ROWS = 10
val COLUMNS = 5
val tableLayout by lazy { TableLayout(this) }
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
textView.text = "ROWS : $ROWS COLUMNS: $COLUMNS"
val lp = TableLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT)
tableLayout.apply {
layoutParams = lp
isShrinkAllColumns = true
}
createTable(ROWS, COLUMNS)
}
fun createTable(rows: Int, cols: Int) {
for (i in 0 until rows) {
val row = TableRow(this)
row.layoutParams = ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT)
for (j in 0 until cols) {
val button = Button(this)
button.apply {
layoutParams = TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT)
text = "R $i C $j"
}
row.addView(button)
}
tableLayout.addView(row)
}
linearLayout.addView(tableLayout)
}
}
希望这会有所帮助。
