如何在Android中制作Double seekbar? [英] How to make double seekbar in android?
问题描述
我正在构建一个android应用程序,用户可以通过seekbar选择最大值.
I am building an android application where the user select the a maximum value by seekbar.
我需要在同一搜寻栏上另外一个按钮,以便用户可以从特定的唯一搜寻栏中选择最大值和最小值.
I need another button on the same seekbar so that user can select maximum and minimum value from a particular unique seekbar.
这是我的单搜寻条代码-
Here is my code of single seek bar -
package com.ui.yogeshblogspot;
public class CustomSeekBarExActivity extends Activity implements OnSeekBarChangeListener{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SeekBar bar=(SeekBar)findViewById(R.id.seekBar1);
bar.setOnSeekBarChangeListener(this);
}
@Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
// TODO Auto-generated method stub
TextView tv=(TextView)findViewById(R.id.textView2);
tv.setText(Integer.toString(progress)+"%");
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
}
这是我的搜索栏的xml代码-
Here is my xml code of seek bar -
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#FFFFFF">
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Choose Your Progress"
android:textColor="#000000"
android:textAppearance="?android:attr/textAppearanceMedium" />
<SeekBar
android:id="@+id/seekBar1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:progressDrawable="@xml/progress"
android:max="100"
android:thumb="@xml/thumb"/>
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
android:gravity="center"
android:layout_gravity="center"
android:paddingTop="10dp"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
推荐答案
Android小部件类库只有一个滑块控件,seekbar只有一个拇指控件.在线进行了一些研究,发现了这个很酷的自定义小部件range-seek-bar.
The Android widget class library has only one slider control, seekbar with only one thumb control. Did some research online and found this cool custom widget, range-seek-bar.
