我正在开发自定义键盘应用程序，我需要在我的应用程序中设置或更改键盘的背景主题或颜色 .their setting.xml 视图，用户可以在其中为键行选择不同的背景主题和不同的颜色。在第一次启动应用程序时它工作正常，但下次自定义键盘显示主题时不会更改。
我正在使用这段代码：
public class SoftKeyboard extends InputMethodService
implements KeyboardView.OnKeyboardActionListener {
static final boolean DEBUG = false;
/**
* This boolean indicates the optional example code for performing
* processing of hard keys in addition to regular text generation
* from on-screen interaction. It would be used for input methods that
* perform language translations (such as converting text entered on
* a QWERTY keyboard to Chinese), but may not be used for input methods
* that are primarily intended to be used for on-screen text entry.
*/
static final boolean PROCESS_HARD_KEYS = true;
private static final int SELECT_PICTURE = 101;
private KeyboardView mInputView;
private CandidateView mCandidateView;
private CompletionInfo[] mCompletions;
private Context context = SoftKeyboard.this;
private StringBuilder mComposing = new StringBuilder();
private boolean mPredictionOn;
private boolean mCompletionOn;
private int mLastDisplayWidth;
private boolean mCapsLock;
private long mLastShiftTime;
private long mMetaState;
private LatinKeyboard mSymbolsKeyboard;
private LatinKeyboard mSymbolsShiftedKeyboard;
private LatinKeyboard mQwertyKeyboard;
private LatinKeyboard mSmilyKeyboard;
private LatinKeyboard mSmilyKeyboard1;
private LatinKeyboard mCurKeyboard;
private String mWordSeparators;
/**
* Main initialization of the input method component. Be sure to call
* to super class.
*/
@Override
public void onCreate() {
super.onCreate();
mWordSeparators = getResources().getString(R.string.word_separators);
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
String name = preferences.getString("Name","");
Log.e("SoftKeyboard - ",""+name+"OnCreate Method Called--");
if(!name.equalsIgnoreCase(""))
{
name = name+" Sethi"; /* Edit the value here*/
}
}
这是我设置或选择颜色或主题的设置类：
public class Setting extends Activity implements OnClickListener {
LinearLayout roar, edge, burst, impact, blue_theme, orange_theme,
green_theme, black_brigthness, white_brightness;
Bundle bundle;
public static boolean isblackBrightness = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.setting);
// ----------UI intilisation---------------------
uiInitilisation();
}
public void uiInitilisation() {
roar = (LinearLayout) findViewById(R.id.ror_LL);
edge = (LinearLayout) findViewById(R.id.edge_LL);
burst = (LinearLayout) findViewById(R.id.burst_LL);
impact = (LinearLayout) findViewById(R.id.impact_LL);
// -------------Themes------------------------------
blue_theme = (LinearLayout) findViewById(R.id.blue_theme_LL);
orange_theme = (LinearLayout) findViewById(R.id.orange_theme_LL);
green_theme = (LinearLayout) findViewById(R.id.green_theme_LL);
// ------------Brightness----------------------------
black_brigthness = (LinearLayout) findViewById(R.id.black_brigthness_LL);
white_brightness = (LinearLayout) findViewById(R.id.white_brigthness_LL);
// --------------On Click Events-------------------
roar.setOnClickListener(this);
edge.setOnClickListener(this);
burst.setOnClickListener(this);
impact.setOnClickListener(this);
// -----------Theme-------------------------------------
blue_theme.setOnClickListener(this);
orange_theme.setOnClickListener(this);
green_theme.setOnClickListener(this);
// ------------------Brightness--------------------------
black_brigthness.setOnClickListener(this);
white_brightness.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.ror_LL:
startActivity(new Intent(Setting.this, MainActivity.class));
break;
case R.id.edge_LL:
startActivity(new Intent(Setting.this, MainActivity.class));
break;
case R.id.burst_LL:
startActivity(new Intent(Setting.this, MainActivity.class));
break;
case R.id.impact_LL:
startActivity(new Intent(Setting.this, MainActivity.class));
break;
case R.id.blue_theme_LL:
Intent i = new Intent(Setting.this,
MainActivity.class);
i.putExtra("color", "blue");
startActivity(i);
break;
case R.id.orange_theme_LL:
Intent i2 = new Intent(Setting.this,
MainActivity.class);
i2.putExtra("color", "orange");
startActivity(i2);
break;
case R.id.green_theme_LL:
Intent i3 = new Intent(Setting.this,
MainActivity.class);
i3.putExtra("color", "green");
startActivity(i3);
break;
case R.id.black_brigthness_LL:
Intent black_britness = new Intent(Setting.this,
MainActivity.class);
black_britness.putExtra("bright", "black");
startActivity(black_britness);
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor editor = preferences.edit();
editor.putString("Name","Harneet");
editor.commit();
isblackBrightness = true ;
Log.e("Black--","Black=="+isblackBrightness);
break;
case R.id.white_brigthness_LL:
Intent white_britness = new Intent(Setting.this,
MainActivity.class);
white_britness.putExtra("bright", "white");
startActivity(white_britness);
isblackBrightness = false;
Log.e("white--","White=="+isblackBrightness);
SharedPreferences preferences1 = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor editor1 = preferences1.edit();
editor1.putString("Name","Arun");
editor1.commit();
break;
}
}
}
无论我是否必须设置小部件，我都没有得到如何做到这一点。
