应用场景在输入框中输入电话点击确定即拨号

    这里只给出activity和配置的代码 布局页面就是一个输入框和一个按钮

   Activity代码

 

package com.example.test;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends Activity {
     private Button button=null;
     private EditText edit=null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button=(Button)this.findViewById(R.id.button);
        edit=(EditText)findViewById(R.id.phoneNum);
        button.setOnClickListener(new buttonOnClickListener());
    }

    private final class buttonOnClickListener implements View.OnClickListener{
		@Override
		public void onClick(View v) {
			  String phoneNum=edit.getText().toString();
			  Intent intent=new Intent();
			  intent.setAction("android.intent.action.CALL");
			  intent.setData(Uri.parse("tel:"+phoneNum));
			  startActivity(intent);
		}
    }

  @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;
    }
    
}
