(本想通过Button中android:background使用drawable资源下的图片作为按钮背景，设计太丑就去掉了Σ(= = !))

 

package com.example.asus.a7gary01;

import android.content.DialogInterface;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    private Button button;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);
        button = (Button) findViewById(R.id.更多);

        button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);

                builder.setItems(getResources().getStringArray(R.array.Gary), new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {

                    }
                });
                builder.show();
            }
