如何使用另一种颜色选择器，而不preferenceActivity？ [英] How can I use another Color Picker without preferenceActivity?

问题描述

我有我的共享prefereces使用颜色选择器。使用默认的ColorPicker我设法acheive我想要什么，但我注意到，没有黑色或白色的颜色。的http://www.yougli.net/android/a-photoshop-like-color-picker-for-your-android-application/
我想利用这个code，但在最后排，他给出了一个例子，在那里我可以看到它是连接到preferenced屏幕。相反，它的我用我自己的活动的按钮在哪里使用共享preferences我可以节省DATAS /值（所以它不是一个preferenceActivity，只是一个活动）。例如点击一个布局的结果：

I have a color picker which I use in sharedPrefereces. With the default colorpicker I managed to acheive what I want, but I noticed there is no black or white colors. http://www.yougli.net/android/a-photoshop-like-color-picker-for-your-android-application/ I would like to use this code but in the last rows, he shows an example, where I can see it is attached to a preferenced Screen. Instead of it I use my own activity with buttons where using shared Preferences I can save datas/values (so its not a preferenceActivity, just an Activity). For example clicking on a layout results:

OptVertexColor = (LinearLayout) findViewById(R.id.OptVC);
        OptVertexColor.setOnClickListener(new View.OnClickListener() {
        @Override
            public void onClick(View v) {
            LoadChartVertexColor(); 
                ColorPickerDialog dlg = new ColorPickerDialog(settings.this,
                            new ColorPickerDialog.OnColorChangedListener() {
                        public void colorChanged(int color) {
                          SaveChartVertexColor("vertexcolor", color);
                        }
                    }, loadedVertexColor);
                    dlg.setTitle("Select new color");

                    dlg.show();
                }
        }); 

显示默认拾色器对话框，我还能再救一个颜色。现在，我怎么可以使用这个没有preference屏和acheive是一回事吗？我试图复制上面这个code中的code，但我coudnt弄清楚如何处理它。

The default color picker dialog appears and I can save a color. Now how can I use this without a preference screen and acheive the same thing? I tried to copy the code above to this code, but I coudnt figure out how to handle it.

public class MySettings extends PreferenceActivity implements OnPreferenceClickListener, ColorPickerDialog.OnColorChangedListener {

    public boolean onPreferenceClick(Preference pref)

    {

        new ColorPickerDialog(this, this, DROIDS_COLOR_KEY, mPrefs.getInt(DROIDS_COLOR_KEY, DROIDS_COLOR_DEFAULT), DROIDS_COLOR_DEFAULT).show();

        return true;

    }

    public void colorChanged(String key, int color)

    {

        ((PreferenceScreen)this.findPreference(SETTINGS_KEY)).getEditor().putInt(key, color).commit();

    }

}

感谢你在前进！

推荐答案

在自己的活动中，添加

implements ColorPickerDialog.OnColorChangedListener

到类声明。

添加到您的类主体：

 public void colorChanged(String key, int color) {
        //create your SharedPreferences and your SharedPreferences.Editor here
        editor.putInt(key, color);
        editor.commit();    
    }

和在点击一个按钮添加监听器：

And in a button click listener add:

new ColorPickerDialog(this, this, DROIDS_COLOR_KEY, mPrefs.getInt(DROIDS_COLOR_KEY, DROIDS_COLOR_DEFAULT), DROIDS_COLOR_DEFAULT).show();

这应该工作。让我知道，如果你我没有回答你的问题，我会看看我能做些什么。
