android之seekbar

做了一个拖动滑块改变数值的demo

下附上代码:

<SeekBar
    android:id="@+id/myseekbar"
    android:layout_width="match_parent"
    android:layout_marginTop="20dp"
    android:thumb="@drawable/slider"
    android:layout_height="wrap_content" />

<TextView
    android:id="@+id/mytext"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="30dp"
    android:layout_marginTop="30dp"
    android:layout_gravity="center"
    android:text="0"
    />

myseek=(SeekBar) findViewById(R.id.myseekbar);
mytext=(TextView)findViewById(R.id.mytext);
myseek.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
    @Override
    public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
        mytext.setText(String.valueOf(i));
    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {

    }

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {

    }
});
