Android custom prompt box, android custom

During development, if you feel that the prompt box provided by the system is not easy to understand, developers can customize the style of the prompt box by themselves, mainly inheriting the Dialog

Program directory structure

Key code

Package com. dzt. custom. dialog; import android. app. dialog; import android. content. context; import android. content. res. resources; import android. util. displayMetrics; import android. view. gravity; import android. view. view; import android. view. window; import android. view. windowManager; import android. widget. textView;/*** custom Dialog box ***/public class CustomDialog extends Dialog implementsandroid. view. view. onClickLi Stener {private static int default_width = 400; // default width: private static int default_height = 200; // default height: private static String mShowText = null; private TextView mText = null; public CustomDialog (Context context) {super (context);} public CustomDialog (Context context, int layout, int style, String msg) {this (context, default_width, default_height, layout, style, msg);} public CustomDialog (Context context, Int width, int height, int layout, int style, String msg) {super (context, style); // setContentView (layout); mShowText = msg; initWidgets (); // set Window Properties window Window = getWindow (); WindowManager. layoutParams params = window. getAttributes (); // set the width, height, density, and alignment float density = getDensity (context); params. width = (int) (width * density); params. height = (int) (height * density); params. gravity = Gravity. CENT ER; window. setAttributes (params) ;}@ Overrideprotected void onStop () {// TODO Auto-generated method stubsuper. onStop (); System. out. println ("stop");}/*** initialize the control */private void initWidgets () {CustomImageButton btn = (CustomImageButton) findViewById (R. id. btn_ OK); btn. setOnClickListener (this); btn = (CustomImageButton) findViewById (R. id. btn_cancel); btn. setOnClickListener (this); mText = (TextView) findVi EwById (R. id. dlg_ TV _text); mText. setText (mShowText);}/*** get display density ** @ param context * @ return */public float getDensity (Context context) {Resources res = context. getResources (); DisplayMetrics dm = res. getDisplayMetrics (); return dm. density;} @ Overridepublic void onClick (View v) {// TODO Auto-generated method stubswitch (v. getId () {case R. id. btn_ OK: if (listener! = Null) listener. onClickOk (); System. out. println ("you click OK button ---------"); break; case R. id. btn_cancel: if (listener! = Null) listener. onClickCancel (); System. out. println ("you click cancel button -------"); break; default: break;} public void setOnClickBtnListener (OnClickBtnListener listener) {this. listener = listener;} private OnClickBtnListener listener = null; public interface OnClickBtnListener {public void onClickOk (); public void onClickCancel ();}}

The listener is set for the two buttons in the prompt box, And the buttons are also customized.

Package com. dzt. custom. dialog; import android. content. context; import android. content. res. typedArray; import android. graphics. canvas; import android. graphics. paint; import android. graphics. paint. align; import android. util. attributeSet; import android. util. log; import android. widget. imageButton;/*** custom ImageButton can set text on ImageButton */public class CustomImageButton extends ImageButton {private static final String TAG = "mimimagebutton_dzt"; private String mtext = ""; private int mcolor = 0; private float mtextsize = 0f; private Paint mpatin; public CustomImageButton (Context context, AttributeSet attrs) {super (context, attrs); initAttrs (attrs );} private void initAttrs (AttributeSet attrs) {TypedArray array = getContext (). obtainStyledAttributes (attrs, R. styleable. customButtonAttrs); mtext = array. getString (R. styleable. customButtonAttrs_textValue); mcolor = array. getColor (R. styleable. customButtonAttrs_textColor, 230); mtextsize = array. getDimension (R. styleable. customButtonAttrs_textSize, 25366f); array. recycle (); // reclaim the resource mpatin = new Paint (); mpatin. setTextAlign (Align. CENTER); Log. d (TAG, "mtextsize =" + mtextsize);} public void setText (String text) {this. mtext = text;} public void setColor (int color) {this. mcolor = color;} public void setTextSize (float textsize) {this. mtextsize = textsize;} @ Overrideprotected void onDraw (Canvas canvas) {super. onDraw (canvas); mpatin. setColor (mcolor); mpatin. setTextSize (mtextsize); canvas. drawText (mtext, canvas. getWidth ()/2, (canvas. getHeight ()/2) + 10, mpatin );}}

It is also very simple to call

@ Overridepublic void onClick (View v) {// TODO Auto-generated method stubswitch (v. getId () {case R. id. btn_show_dialog: customDialog = new CustomDialog (this, R. layout. dialog_layout, R. style. dialogTheme, getResources (). getString (R. string. text_show); customDialog. show (); customDialog. setOnClickBtnListener (new OnClickBtnListener () {@ Overridepublic void onClickOk () {// TODO Auto-generated method stubSystem. out. println ("you click OK button"); // process the operation when you click OK //............... customDialog. cancel () ;}@ Overridepublic void onClickCancel () {// TODO Auto-generated method stubSystem. out. println ("you click cancel button"); // process the operation when you click Cancel //................... customDialog. cancel () ;}}); break; default: break ;}}
