1、自定义T9网格 ViewGroup实现虚拟键盘
package t9.launcher.tos.com.toslaunchert9search;import android.content.Context;import android.text.Editable;import android.text.TextUtils;import android.text.TextWatcher;import android.util.AttributeSet;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;import android.widget.TextView;/** * T9拨号盘 3*4 T9拨号盘 * Created by ferris on 2016/7/15. */public class AppSearchT9View extends ViewGroup implements View.OnClickListener { private int col=3; private int row=4; private TextView mT9InputEt; private ImageView mDialDeleteBtn; public void setTextInput(TextView mT9InputEt){ this.mT9InputEt=mT9InputEt; mT9InputEt.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } @Override public void afterTextChanged(Editable s) { if (null != mOnT9TelephoneDialpadView) { String inputStr=s.toString(); mOnT9TelephoneDialpadView.onDialInputTextChanged(inputStr); } } }); } private OnT9TelephoneDialpadView mOnT9TelephoneDialpadView = null; public OnT9TelephoneDialpadView getOnT9TelephoneDialpadView() { return mOnT9TelephoneDialpadView;

} v.setOnClickListener(this); } } /** * Interface definition for a callback to be invoked when a * T9TelephoneDialpadView is operated. */ public interface OnT9TelephoneDialpadView { void onAddDialCharacter(String addCharacter); void onDeleteDialCharacter(String deleteCharacter); void onDialInputTextChanged(String curCharacter); void onHideT9TelephoneDialpadView(); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { //measure每个图标的大小 int widthMode = View.MeasureSpec.getMode(widthMeasureSpec); int heightMode = View.MeasureSpec.getMode(heightMeasureSpec); int width = View.MeasureSpec.getSize(widthMeasureSpec); int height = View.MeasureSpec.getSize(heightMeasureSpec); int paddingLeft=getPaddingLeft();

v.measure(childWidthSpec, childHeightSpec); } } setMeasuredDimension(width, height); } @Override protected void onLayout(boolean changed, int l, int t, int r, int b) { // layout child int paddingLeft=getPaddingLeft(); int paddingRight=getPaddingRight(); int padingTop=getPaddingTop(); int padingBottom=getPaddingBottom(); int releaseWidth=(getMeasuredWidth()-paddingLeft-paddingRight)/col; int releaseHeiht=(getMeasuredHeight()-padingTop-padingBottom)/row;

left=currentCol*releaseWidth+iconOffsetX; top=currentRow*releaseHeiht+iconOffsetY; if (v != null) { v.layout(left, top, left+releaseWidth, top+releaseHeiht); } } } @Override public void onClick(View v) { switch (v.getId()) { case R.id.dial_delete_btn: deleteSingleDialCharacter(); break; case R.id.dialNum0: case R.id.dialNum1: case R.id.dialNum2: case R.id.dialNum3: case R.id.dialNum4: case R.id.dialNum5: case R.id.dialNum6: case R.id.dialNum7: case R.id.dialNum8: case R.id.dialNum9: addSingleDialCharacter(v.getTag().toString()); break; default: break; } } public void deleteSingleDialCharacter() { String curInputStr = mT9InputEt.getText().toString(); if (curInputStr.length() > 0) { String deleteCharacter = curInputStr.substring( curInputStr.length() - 1, curInputStr.length()); if (null != mOnT9TelephoneDialpadView) { mOnT9TelephoneDialpadView .onDeleteDialCharacter(deleteCharacter); } String newCurInputStr=curInputStr.substring(0,curInputStr.length() - 1); mT9InputEt.setText(newCurInputStr); //mT9InputEt.setSelection(newCurInputStr.length());// if(TextUtils.isEmpty(newCurInputStr)){// ViewUtil.hideView(mDialDeleteBtn);// }else{// ViewUtil.showView(mDialDeleteBtn);// } } } private void addSingleDialCharacter(String addCharacter) { String preInputStr = mT9InputEt.getText().toString();

package t9.launcher.tos.com.toslaunchert9search;import android.content.Context;import android.graphics.Canvas;import android.text.TextUtils;import android.util.AttributeSet;import android.widget.TextView;/** * 带下划线的textView * Created by ferris on 2016/7/15. */public class LineTextView extends TextView {// Paint mPaint=new Paint(); public LineTextView(Context context) { super(context); init(); } public LineTextView(Context context, AttributeSet attrs) { super(context, attrs); init(); } public LineTextView(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); init(); } public void init(){// mPaint.setStyle(Paint.Style.STROKE);//设置非填充// mPaint.setStrokeWidth(1);//笔宽5像素// mPaint.setColor(Color.BLACK);//设置为红笔// mPaint.setAntiAlias(true);//锯齿不显示 } @Override protected void onDraw(Canvas canvas) { if(TextUtils.isEmpty(getText())){ super.onDraw(canvas); return; } canvas.save(); super.onDraw(canvas); canvas.drawLine(0,getMeasuredHeight(),getMeasuredWidth(),getMeasuredHeight(),getPaint()); canvas.restore(); }}更多相关文章
