我怎么知道android中音量的最大值是多少？

Question

function Menu(x, y, z) {    
    this.createMenu = function(x, y) {
        return x + y;
    }    
}

var m = new Menu;

console.log(m.createMenu(3, 5));
m.createMenu = function(x, y) { return x * y; };
console.log(m.createMenu(3, 5));

Answer 1

试试这个。

audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC),0);`
