這篇文章給大家分享的是有關(guān)Android如何實(shí)現(xiàn)點(diǎn)擊持續(xù)錄音，松開(kāi)結(jié)束錄音并實(shí)現(xiàn)隨著分貝的大小改變圖片的內(nèi)容。小編覺(jué)得挺實(shí)用的，因此分享給大家做個(gè)參考，一起跟隨小編過(guò)來(lái)看看吧。
顯示錄音大小的DIALOG實(shí)現(xiàn)
public class VioceDomio {

LayoutInflater inflater = LayoutInflater.from(mContext);
View view=inflater.inflate(R.layout.voice_chage,null);
vioce_show=(ImageView) view.findViewById(R.id.vioce_show);
adialogbuile.setView(view);
dialog = adialogbuile.create();
dialog.show();
dialog. getWindow().setLayout(500, 450);
}
public void HideRecordingDialog() {
if(dialog!=null && dialog.isShowing()) {
dialog.dismiss();
dialog=null;
}
}
public void ChangeRecordingDialog(double db) { //根據(jù)錄音的分貝改變大小
if(db>=1 && db<=18) {
vioce_show.setImageResource(R.drawable.voicesearch_feedback001);
}else if(db>=19 && db<=37) {
vioce_show.setImageResource(R.drawable.voicesearch_feedback002);
}else if(db>=19 && db<=37) {
vioce_show.setImageResource(R.drawable.voicesearch_feedback003);
}

}
}Dialog加載的XML頁(yè)面實(shí)現(xiàn)
