我搜索了一些主题,但没有找到解决我问题的方法.
public class Series implements Parcelable {
private String name;
private int numOfSeason;
private int numOfEpisode;
/** Constructors and Getters/Setters have been removed to make reading easier **/
public Series(Parcel in) {
String[] data = new String[3];
in.readStringArray(data);
this.name = data[0];
this.numOfSeason = Integer.parseInt(data[1]);
this.numOfEpisode = Integer.parseInt(data[2]);
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeStringArray(new String[] { this.name,
String.valueOf(this.numOfSeason),
String.valueOf(this.numOfEpisode) });
}
private void readFromParcel(Parcel in) {
name = in.readString(); …我有一个按钮的ArrayList,我的OCL需要知道我按下了哪个索引.计划是这样的:
MyOnClickListener onClickListener = new MyOnClickListener() {
@Override
public void onClick(View v) {
Intent returnIntent = new Intent();
returnIntent.putExtra("deleteAtIndex",idx);
setResult(RESULT_OK, returnIntent);
finish();
}
};
for (int i =0;i<buttonList.size();i++) {
buttonList.get(i).setText("Remove");
buttonList.get(i).setOnClickListener(onClickListener);
}
我的OCL实现需要怎么样？
目前我有这个:
public class MyOnClickListener implements OnClickListener{
int index;
public MyOnClickListener(int index)
{
this.index = index;
}
@Override
public void onClick(View arg0) {
}
}
但是,我不确定我在OCL的构造函数中需要做什么,以及覆盖onClick函数.
我有一个具有相当大边界的JTextField,但是文本的行为并不像我想要的那样.

编辑:使用JTextArea修复我的问题.谢谢.
我正在寻找在Android设备上播放音频的可能性,这让我既可以使用seekTo功能(踩在音频文件的指定部分),也可以使用setPlaybackRate(加快/降低播放速率).但是,看看Android提供的媒体类我只能找到以下内容.
SoundPool:缺乏seekTo
AudioTrack:缺乏seekTo
MediaPlayer:缺乏setRate
有没有办法在Android中播放音频而不必自己编写太多代码来提供这些功能？
使用 Kotlin 和 kapt 运行 Gradle 时，我收到以下错误消息。
