IntentActionUtil【Intent的常见作用的工具类】

版权声明：本文为博主原创文章，未经博主允许不得转载。

前言

主要用于通过Intent调用手机本地软件打开文件（doc、xsl、pdf、ppt、mp3、mp4等格式）、安装apk、发送邮件、拨打电话、发送短信、打开地图。

因为需要用到android.permission.READ_EXTERNAL_STORAGE权限，所以依赖《Android6.0运行时权限(基于RxPermission开源库)》。

效果图

IntentActionUtil

在AndroidManifest.xml中添加权限

<!-- *****************IntentActionUtil【Intent的常见作用的工具类】***************** -->
<!-- 在SD卡中创建与删除文件权限 -->
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
<!-- 向SD卡写入数据权限 -->
<uses-permission android:name="android.permission.REORDER_TASKS"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

添加运行时权限的处理（本demo中采用的是修改targetSDKVersion=22）

三、使用方法

tv_openEmail.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent = IntentActionUtil.getEmailIntent("wangxxxxxx@126.com");
if(IntentActionUtil.isIntentAvailable(MainActivity.this,intent)){
MainActivity.this.startActivity(intent);
}else{
Toast.makeText(MainActivity.this, "无法打开，请安装手机邮箱软件", Toast.LENGTH_SHORT).show();
}
}
});

tv_openWeb.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent = IntentActionUtil.getWebViewIntent("http://www.baidu.com");
if(IntentActionUtil.isIntentAvailable(MainActivity.this,intent)){
MainActivity.this.startActivity(intent);
}else{
Toast.makeText(MainActivity.this, "无法打开，请安装手机浏览器软件", Toast.LENGTH_SHORT).show();
}
}
});

tv_openMap.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent = IntentActionUtil.getMapViewIntent(116.398064,39.913703);
if(IntentActionUtil.isIntentAvailable(MainActivity.this,intent)){
MainActivity.this.startActivity(intent);
}else{
Toast.makeText(MainActivity.this, "无法打开，请安装手机地图软件", Toast.LENGTH_SHORT).show();
}
}
});

tv_openTel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent = IntentActionUtil.getPhoneIntent("10010");
if(IntentActionUtil.isIntentAvailable(MainActivity.this,intent)){
MainActivity.this.startActivity(intent);
}
}
});

tv_openSMS.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent = IntentActionUtil.getSMSIntent("10010","");
if(IntentActionUtil.isIntentAvailable(MainActivity.this,intent)){
MainActivity.this.startActivity(intent);
}
}
});

tv_openAudio.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String filePath = Environment.getExternalStorageDirectory() + "/intentFile/" + "videodemo.m4a";
Intent intent = new Intent();
intent = IntentActionUtil.openFileIntent(filePath);
if(intent != null){
MainActivity.this.startActivity(intent);
}else{
Toast.makeText(MainActivity.this,"文件不存在",Toast.LENGTH_SHORT).show();
}
}
