每日总结

1.SeekBar(拖动条)

布局省略

重点是 private SeekBar sb_normal;

private TextView txt_cur;

private Context mContext;

private void bindViews() {
        sb_normal = (SeekBar) findViewById(R.id.sb_normal);
        txt_cur = (TextView) findViewById(R.id.txt_cur);
        sb_normal.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                txt_cur.setText("当前进度值:" + progress + "  / 100 ");
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {
                Toast.makeText(mContext, "触碰SeekBar", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {
                Toast.makeText(mContext, "放开SeekBar", Toast.LENGTH_SHORT).show();
            }
        });
    }
