package com.li.intentcaseproject;

 

import android.net.Uri;

import android.os.Bundle;

import android.app.Activity;

import android.content.Intent;

import android.view.Menu;

import android.view.MenuItem;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.EditText;

import android.support.v4.app.NavUtils;

 

public class MyIntentCaseDemo extends Activity {

  private Button mybut = null;

  private EditText tel = null;

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        super.setContentView(R.layout.main);

        this.mybut = (Button)super.findViewById(R.id.mybut);

        this.tel = (EditText)super.findViewById(R.id.tel);

        this.mybut.setOnClickListener(new OnClickListenerImpl());

       

    }

    private class OnClickListenerImpl implements OnClickListener{

     public void onClick(View v) {

       String telStr = MyIntentCaseDemo.this

            .tel.getText().toString();  //取得输入信息

       Uri uri = Uri.parse("tel:" + telStr); //设置要操作的路径

       Intent it = new Intent();

       it.setAction(Intent.ACTION_CALL);  //设置要操作的Action

       it.setData(uri); //要设置的数据

       MyIntentCaseDemo.this.startActivity(it);    //执行跳转

      

     }

    }

}
