本以為是一個簡單的電話撥號器，還是學到了不少東西，所以還是學到了不少東西，懂得了android許可權 Uri.parse的幾種用法：
不多說上代碼：
package com.djf.phone;import android.app.Activity;import android.content.Intent;import android.net.Uri;import android.os.Bundle;import android.text.TextUtils;import android.view.View;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}public void myclick(View view) {EditText mEditText = (EditText) findViewById(R.id.et_number);String number = mEditText.getText().toString().trim();boolean result = TextUtils.isEmpty(number);if (result) {Toast.makeText(this, "電話號碼為空白", 0).show();}else {Intent intent = new Intent();intent.setAction(Intent.ACTION_CALL);intent.setData(Uri.parse("tel:"+number));startActivity(intent);}}}
以上紅色部分主要涉及Uri.prase的幾種用法
“tel:”一定不能省略
下面附上uri.prase的重要用法
1，調web瀏覽器
Uri myBlogUri = Uri.parse("http://xxxxx.com");
returnIt = new Intent(Intent.ACTION_VIEW, myBlogUri);
2，地圖
Uri mapUri = Uri.parse("geo:38.899533,-77.036476");
returnIt = new Intent(Intent.ACTION_VIEW, mapUri);
3，調撥打到電話介面
Uri telUri = Uri.parse("tel:100861");
returnIt = new Intent(Intent.ACTION_DIAL, telUri);
4，直接撥打到電話
Uri callUri = Uri.parse("tel:100861");
returnIt = new Intent(Intent.ACTION_CALL, callUri);
5，卸載
Uri uninstallUri = Uri.fromParts("package", "xxx", null);
returnIt = new Intent(Intent.ACTION_DELETE, uninstallUri);
6，安裝
Uri installUri = Uri.fromParts("package", "xxx", null);
returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri);
7，播放
Uri playUri = Uri.parse("file:///sdcard/download/everything.mp3");
returnIt = new Intent(Intent.ACTION_VIEW, playUri);
8，調用發郵件
Uri emailUri = Uri.parse("mailto:[email protected]");
returnIt = new Intent(Intent.ACTION_SENDTO, emailUri);
9，發郵件
returnIt = new Intent(Intent.ACTION_SEND);
String[] tos = { "[email protected]" };
String[] ccs = { "[email protected]" };
returnIt.putExtra(Intent.EXTRA_EMAIL, tos);
returnIt.putExtra(Intent.EXTRA_CC, ccs);
returnIt.putExtra(Intent.EXTRA_TEXT, "body");
returnIt.putExtra(Intent.EXTRA_SUBJECT, "subject");
returnIt.setType("message/rfc882");
Intent.createChooser(returnIt, "Choose Email Client");
10，發簡訊
Uri smsUri = Uri.parse("tel:100861");
returnIt = new Intent(Intent.ACTION_VIEW, smsUri);
returnIt.putExtra("sms_body", "yyyy");
returnIt.setType("vnd.android-dir/mms-sms");
11，直接發郵件
Uri smsToUri = Uri.parse("smsto://100861");
returnIt = new Intent(Intent.ACTION_SENDTO, smsToUri);
returnIt.putExtra("sms_body", "yyyy");
12，發多媒體訊息
Uri mmsUri = Uri.parse("content://media/external/images/media/23");
