我是靠谱客的博主丰富果汁，最近开发中收集的这篇文章主要介绍打招呼hello，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

package com.example.texthello1;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends Activity {
	private Button button1;
	private EditText ET_Name;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		Button button1 = (Button) findViewById(R.id.button1);
		ET_Name=(EditText) findViewById(R.id.ET_Name);
		button1.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				String name = ET_Name.getText().toString();
				Toast.makeText(MainActivity.this, "Hello" + name, Toast.LENGTH_LONG).show();
			}
		});
				
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

	public Button getButton1() {
		return button1;
	}

	public void setButton1(Button button1) {
		this.button1 = button1;
	}

}
