android中一些常用的VIEW动作类型

// 实例一个intent对象
Intent intent = new Intent();
// 设置动作事件为Action_View;
intent.setAction(android.content.Intent.ACTION_VIEW);
String fileName = file.getName();
if (justFileEndWith(fileName, this.getResources().getStringArray(
R.array.fileEndWithImage))) {
intent.setDataAndType(Uri.fromFile(file), "image/*");
} else if (justFileEndWith(fileName, this.getResources()
.getStringArray(R.array.fileEndWithAudio))) {
intent.setDataAndType(Uri.fromFile(file), "audio/*");
} else if (justFileEndWith(fileName, this.getResources()
.getStringArray(R.array.fileEndWithVideo))) {
intent.setDataAndType(Uri.fromFile(file), "video/*");
}
else if(fileName.endsWith(".apk"))
{
//安装APK文件
intent.setDataAndType(Uri.fromFile(file),"application/vnd.android.package-archive");
}
else if(fileName.endsWith(".txt"))
{
intent.setDataAndType(Uri.fromFile(file),"txt/*");
}
this.startActivity(intent);
