本文实例为大家分享了Android实现计算器界面的具体代码，供大家参考，具体内容如下

XML文件：

<?xml version="1.0" encoding="utf-8"?><GridLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" android:rowCount="6" android:columnCount="4" android:id="@+id/root"> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_columnSpan="4" android:textSize="50sp" android:layout_marginLeft="2pt" android:layout_marginRight="2pt" android:padding="3pt" android:layout_gravity="right" android:background="#eee" android:textColor="#000" android:text="0" /> <Button android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_columnSpan="4" android:text="清除"/> </GridLayout>

MainActivity:

package learn.li.com.learnthree; import android.os.Handler;import android.os.Message;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.Gravity;import android.widget.Button;import android.widget.GridLayout;import android.widget.TextView; import java.util.Timer;import java.util.TimerTask; public class MainActivity extends AppCompatActivity { GridLayout gridLayout; String[] chars = new String[]{ "7","8","9","÷", "4","5","6","x", "1","2","3","-", ".","0","=","=" }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); gridLayout = (GridLayout)findViewById(R.id.root); for(int i = 0;i < chars.length;i++){ Button bn = new Button(this); bn.setText(chars[i]); bn.setTextSize(40); bn.setPadding(5,35,5,35); GridLayout.Spec rowSpec = GridLayout.spec(i/4 + 2); GridLayout.Spec columnSpec = GridLayout.spec(i%4); GridLayout.LayoutParams params = new GridLayout.LayoutParams(rowSpec,columnSpec); params.setGravity(Gravity.FILL); gridLayout.addView(bn,params); } }}

效果：
