本文主要是介绍Android GridLayout 表格布局,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
GridLayout表格布局以 行x列 的形式管理UI组件,
XMLandroid:columnCount="5" //设置列数android:rowCount="5"//设置行数android:layout_columnSpan="4" //横向跨几列 android:layout_rowSpan="4"代码
mGridLayout.setColumnCount(int);//设置列数 mGridLayout.setRowCount(int);//设置行数
package shortcut.song.com.myapplication;import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.Gravity; import android.widget.Button; import android.widget.GridLayout;public class GridLayoutActivity extends AppCompatActivity {GridLayout mGridLayout;String[] chars = new String[]{"7", "8", "9", "/","4", "5", "6", "*","1", "2", "3", "-",".", "0", "=", "+" };@Override protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_grid_layout);mGridLayout = (GridLayout)findViewById(R.id.gridlayout1);for( int i=0; i<chars.length; i++ ){Button btn = new Button(this);btn.setText(chars[i]);btn.setTextSize(40);btn.setMinWidth(30);btn.setPadding(5, 35, 5, 35);//指定该组件所在的行 GridLayout.Spec rowSpec = GridLayout.spec(i / 4 + 2);//指定该组件所在的列 GridLayout.Spec columnSpec = GridLayout.spec(i % 4);GridLayout.LayoutParams params = new GridLayout.LayoutParams(rowSpec, columnSpec);params.setGravity(Gravity.FILL);mGridLayout.addView(btn, params);}} }
<?xml version="1.0" encoding="utf-8"?> <GridLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:columnCount="4" android:rowCount="6" android:id="@+id/gridlayout1" ><TextView android:id="@+id/val_text" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_columnSpan="4" android:layout_marginLeft="2pt" android:layout_marginRight="2pt" android:layout_gravity="right" android:padding="3pt" android:text="0" /><Button android:id="@+id/clear_btn" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_columnSpan="4" android:text="Clear" /> </GridLayout>
