的Android挑意圖

Question

我想挑這些3種的MIME類型的文件，它似乎並沒有工作

Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT); 
photoPickerIntent.setType("image/*, video/*, audio/*"); 

有人建議我該怎麼辦呢？

Answer 1

寫下面的代碼而不是你的代碼，它可能會幫助你。

private static final int PICTURE = 0; 
private static final int VIDEO = 1; 
private static final int AUDIO = 2; 


Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT); 
String title = GET_PICTURE; 

if (this.mediaType == PICTURE) { 
    photoPickerIntent.setType("image/*"); 
    title = "GET_PICTURE"; 
}else if (this.mediaType == VIDEO) { 
    photoPickerIntent.setType("video/*");  
    title = "GET_VIDEO"; 
}else if (this.mediaType == AUDIO) { 
    photoPickerIntent.setType("audio/*");  
    title = "GET_AUDIO"; 
}
