如何在不使用XML的情況下向自定義對話框添加搜索欄

Question

此類是我在應用程序中調用的對話框，它的工作原理很好，它的中心有一個大黑點，該對話框不需要XML文件。 我想向此對話框添加一個搜索欄，因為我想在滾動搜索欄時更改剛才提到的點的大小。

public class StrokePicker extends Dialog {

StrokePicker strokepicker;

public StrokePicker(Context context) {
    super(context);
}

public class StrokePickerView extends View {

    Paint Stroke;
    SeekBar seekbar;

    private static final int mCENTER= 32;

    public StrokePickerView(Context context) {
        super(context);
        Stroke = new Paint(Paint.ANTI_ALIAS_FLAG);
        Stroke.setStyle(Paint.Style.FILL);
        Stroke.setColor(Color.BLACK);

    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        Paint paint = new Paint();
        paint.setColor(Color.WHITE);
        canvas.drawCircle(canvas.getWidth()/2-mCENTER, canvas.getHeight()/2-mCENTER*3, mCENTER, Stroke);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        setMeasuredDimension(125 * 2, 100 * 2);
    }
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    LinearLayout layout = new LinearLayout(getContext());
    SeekBar seekbar;
    layout.setOrientation(LinearLayout.VERTICAL);
    layout.setGravity(Gravity.CENTER);
    layout.setPadding(10, 10, 10, 10);
    layout.addView(new StrokePickerView(getContext()),
            new LinearLayout.LayoutParams(
                    LinearLayout.LayoutParams.WRAP_CONTENT,
                    LinearLayout.LayoutParams.WRAP_CONTENT));

    setContentView(layout);
    setTitle("Grosor");
}

}

我沒有找到有關如何在不使用XML的情況下添加搜索欄的信息，我們將不勝感激。 再見，謝謝。

嘗試創建一個SeekBarPreference

要么

builder.setView(View v); here is how you can use it.

LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.yourLayoutId, (ViewGroup) findViewById(R.id.yourLayoutRoot));
AlertDialog.Builder builder = new AlertDialog.Builder(this)
.setView(layout);
AlertDialog alertDialog = builder.create();
alertDialog.show();
SeekBar sb = (SeekBar)layout.findViewById(R.id.yourSeekBar);
sb.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser){
        //Do something here with new value
    }
});
