最近有做一个android项目,里面有使用到在播放视频时可以跳播,同时动态显示播放时间。类似于下图 的效果,我只是抽取其中的一部分做展示,刚接到这个事时也是在网上一通找,最后没找到!而且还碰到有些朋友和我有一样的需求,不知该如何做!现在我分享下自己做的!做的不好,多多包涵!因为上传不了附件,就直接贴代码了!

1 :第一个类是自定义的一个类 也就是SeekBar上方会跟随其一块移动的控件,其实非常简单的一个类 package com.example.textmovebyseekbar; import android.content.Context; import android.util.AttributeSet; import android.view.ViewGroup; //import android.widget.AbsoluteLayout; public class TextMoveLayout extends ViewGroup { public TextMoveLayout(Context context) { super (context); // TODO Auto-generated constructor stub } public TextMoveLayout(Context context, AttributeSet attrs, int defStyle) { super (context, attrs, defStyle); // TODO Auto-generated constructor stub } public TextMoveLayout(Context context, AttributeSet attrs) { super (context, attrs); // TODO Auto-generated constructor stub } @Override protected void onLayout( boolean changed, int l, int t, int r, int b) { // TODO Auto-generated method stub } } |

2 : 第二类就是MainActivity了,代码很简单!稍微看下就懂的了~ package com.example.textmovebyseekbar; import android.app.Activity; import android.graphics.Color; import android.os.Bundle; import android.view.ViewGroup; import android.widget.SeekBar; import android.widget.TextView; public class MainActivity extends Activity { private SeekBar seekbar = null ; private String startTimeStr = "19:30:33" ; private String endTimeStr = "21:23:21" ; private TextView text, startTime, endTime; /** * 视频组中第一个和最后一个视频之间的总时长 */ private int totalSeconds = 0 ; /** * 屏幕宽度 */ private int screenWidth; /** * 自定义随着拖动条一起移动的空间 */ private TextMoveLayout textMoveLayout; private ViewGroup.LayoutParams layoutParams; /** * 托动条的移动步调 */ private float moveStep = 0 ; @Override protected void onCreate(Bundle savedInstanceState) { super .onCreate(savedInstanceState); setContentView(R.layout.video_fast_search); screenWidth = getWindowManager().getDefaultDisplay().getWidth(); text = new TextView( this ); text.setBackgroundColor(Color.rgb( 245 , 245 , 245 )); text.setTextColor(Color.rgb( 0 , 161 , 229 )); text.setTextSize( 16 ); layoutParams = new ViewGroup.LayoutParams(screenWidth, 50 ); textMoveLayout = (TextMoveLayout) findViewById(R.id.textLayout); textMoveLayout.addView(text, layoutParams); text.layout( 0 , 20 , screenWidth, 80 ); /** * findView */ seekbar = (SeekBar) findViewById(R.id.seekbar); startTime = (TextView) findViewById(R.id.start_time); endTime = (TextView) findViewById(R.id.end_time); /** * setListener */ seekbar.setOnSeekBarChangeListener( new OnSeekBarChangeListenerImp()); searchVideos(); } public void searchVideos() { startTime.setText(startTimeStr); endTime.setText(endTimeStr); text.setText(startTimeStr); totalSeconds = totalSeconds(startTimeStr, endTimeStr); seekbar.setEnabled( true ); seekbar.setMax(totalSeconds); seekbar.setProgress( 0 ); moveStep = ( float ) ((( float ) screenWidth / ( float ) totalSeconds) * 0.8 ); } private class OnSeekBarChangeListenerImp implements SeekBar.OnSeekBarChangeListener { // 触发操作,拖动 public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { text.layout(( int ) (progress * moveStep), 20 , screenWidth, 80 ); text.setText(getCheckTimeBySeconds(progress, startTimeStr)); } // 表示进度条刚开始拖动,开始拖动时候触发的操作 public void onStartTrackingTouch(SeekBar seekBar) { } // 停止拖动时候 public void onStopTrackingTouch(SeekBar seekBar) { // TODO Auto-generated method stub } } /** * 计算连个时间之间的秒数 */ private static int totalSeconds(String startTime, String endTime) { String[] st = startTime.split( ":" ); String[] et = endTime.split( ":" ); int st_h = Integer.valueOf(st[ 0 ]); int st_m = Integer.valueOf(st[ 1 ]); int st_s = Integer.valueOf(st[ 2 ]); int et_h = Integer.valueOf(et[ 0 ]); int et_m = Integer.valueOf(et[ 1 ]); int et_s = Integer.valueOf(et[ 2 ]); int totalSeconds = (et_h - st_h) * 3600 + (et_m - st_m) * 60 + (et_s - st_s); return totalSeconds; } /** * 根据当前选择的秒数还原时间点 * * @param args */ private static String getCheckTimeBySeconds( int progress, String startTime) { String return_h = "" , return_m = "" , return_s = "" ; String[] st = startTime.split( ":" ); int st_h = Integer.valueOf(st[ 0 ]); int st_m = Integer.valueOf(st[ 1 ]); int st_s = Integer.valueOf(st[ 2 ]); int h = progress / 3600 ; int m = (progress % 3600 ) / 60 ; int s = progress % 60 ; if ((s + st_s) >= 60 ) { int tmpSecond = (s + st_s) % 60 ; m = m + 1 ; if (tmpSecond >= 10 ) { return_s = tmpSecond + "" ; } else { return_s = "0" + (tmpSecond); } } else { if ((s + st_s) >= 10 ) { return_s = s + st_s + "" ; } else { return_s = "0" + (s + st_s); } } if ((m + st_m) >= 60 ) { int tmpMin = (m + st_m) % 60 ; h = h + 1 ; if (tmpMin >= 10 ) { return_m = tmpMin + "" ; } else { return_m = "0" + (tmpMin); } } else { if ((m + st_m) >= 10 ) { return_m = (m + st_m) + "" ; } else { return_m = "0" + (m + st_m); } } if ((st_h + h) < 10 ) { return_h = "0" + (st_h + h); } else { return_h = st_h + h + "" ; } return return_h + ":" + return_m + ":" + return_s; } } |

3: 接下来这个就是布局文件了,其中会用到一些色值!之后我会贴出来,还有使用的图片和其他的xml文件 <? xml version = "1.0" encoding = "utf-8" ?> < LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:layout_width = "match_parent" android:layout_height = "match_parent" android:background = "@color/bg_whitef5" android:orientation = "vertical" > < LinearLayout android:layout_width = "fill_parent" android:layout_height = "wrap_content" android:orientation = "vertical" > < com.example.textmovebyseekbar.TextMoveLayout android:id = "@+id/textLayout" android:layout_width = "fill_parent" android:layout_height = "40dp" /> < SeekBar android:id = "@+id/seekbar" android:layout_width = "fill_parent" android:layout_height = "wrap_content" android:focusable = "true" android:maxHeight = "4dp" android:minHeight = "4dp" android:paddingLeft = "5dp" android:paddingRight = "5dp" android:progressDrawable = "@drawable/po_seekbar" android:thumb = "@drawable/seekbar_thumb" /> </ LinearLayout > < RelativeLayout android:layout_width = "fill_parent" android:layout_height = "wrap_content" > < TextView android:id = "@+id/start_time" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:layout_alignParentLeft = "true" android:layout_marginLeft = "14dp" android:textColor = "@color/bg_lin_95" /> < TextView android:id = "@+id/end_time" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:layout_alignParentRight = "true" android:layout_marginRight = "14dp" android:textColor = "@color/bg_lin_95" /> </ RelativeLayout > </ LinearLayout > |

5: android:progressDrawable="@drawable/po_seekbar"这句会引用一个xml文件 <? xml version = "1.0" encoding = "utf-8" ?> < layer-list xmlns:android = "http://schemas.android.com/apk/res/android" > < item android:id = "@*android:id/background" > < shape > < solid android:color = "#c6c6c6" /> </ shape > </ item > < item android:id = "@*android:id/secondaryProgress" > < clip > < shape > < solid android:color = "#c6c6c6" /> </ shape > </ clip > </ item > < item android:id = "@*android:id/progress" > < clip > < shape > < solid android:color = "#06a7fa" /> </ shape > </ clip > </ item > </ layer-list > |

6:android:thumb="@drawable/seekbar_thumb"也会引用一个xml文件 这其中又有用到两张图片 <? xml version = "1.0" encoding = "utf-8" ?> < selector xmlns:android = "http://schemas.android.com/apk/res/android" > < item android:drawable = "@drawable/video_fast_search_nomal" android:state_focused = "true" android:state_pressed = "false" /> < item android:drawable = "@drawable/video_fast_search_press" android:state_focused = "true" android:state_pressed = "true" /> < item android:drawable = "@drawable/video_fast_search_press" android:state_focused = "false" android:state_pressed = "true" /> < item android:drawable = "@drawable/video_fast_search_nomal" /> </ selector > |
