Android带文字的ImageButton实现
实际上，ImageButton是不能添加文字的，所以我选择将ImageView控件和TextView控件封装在一个LinearLayout里面，整个LinearLayout就是一个按钮，然后对它监听单击等动作。
首先贴上layout.xml里面的布局设计：view sourceprint?01<LinearLayout02????????android:layout_width="wrap_content"03????????android:layout_height="wrap_content"04????????android:orientation="vertical"05????????android:id="@+id/bt"> 06????????<ImageView07????????????android:id="@+id/ib"08????????????android:layout_width="wrap_content"09????????????android:layout_height="wrap_content"10????????????android:src="@drawable/ringlove"11????????????android:background="#00000000"12????????/> 13????????<TextView14????????????android:id="@+id/tv"15????????????android:layout_width="wrap_content"16????????????android:layout_height="wrap_content"17????????????android:text="@string/cs"18????????????android:paddingLeft="20px"19????????/> 20</LinearLayout>然后是java代码实现：（注意，m_ll.setClickable(true);这句一定不能少）view sourceprint?01package com.droidX.wcs233; 02??03import android.app.Activity; 04import android.graphics.Color; 05import android.os.Bundle; 06import android.view.MotionEvent; 07import android.view.View; 08import android.view.View.OnClickListener; 09import android.view.View.OnTouchListener; 10import android.widget.LinearLayout; 11import android.widget.Toast; 12??13public class testActivity extends Activity { 14????LinearLayout m_ll; 15????/** Called when the activity is first created. */16????@Override17????public void onCreate(Bundle savedInstanceState) { 18????????super.onCreate(savedInstanceState); 19????????setContentView(R.layout.main); 20????????m_ll=(LinearLayout)findViewById(R.id.bt); 21????????m_ll.setClickable(true); 22????????m_ll.setOnClickListener(ocl); 23????????m_ll.setOnTouchListener(otl); 24????} 25??????26????public OnClickListener ocl=new OnClickListener() { 27??????????28????????@Override29????????public void onClick(View v) { 30????????????// TODO Auto-generated method stub 31????????????Toast.makeText(getApplicationContext(), "yes", Toast.LENGTH_SHORT).show(); 32????????} 33????}; 34??????35????public OnTouchListener otl=new OnTouchListener() { 36??????????37????????@Override38????????public boolean onTouch(View v, MotionEvent event) { 39????????????// TODO Auto-generated method stub 40????????????if(event.getAction()==MotionEvent.ACTION_DOWN) 41????????????{ 42????????????????m_ll.setBackgroundColor(Color.rgb(127,127,127)); 43????????????} 44????????????else if(event.getAction()==MotionEvent.ACTION_UP) 45????????????{ 46????????????????m_ll.setBackgroundColor(Color.TRANSPARENT); 47????????????} 48????????????return false; 49????????} 50????}; 51}这样就可以了。另外，为了使“按钮”美观，大家在选择图片的时候，尽量选择长宽不一样的，适合需要的比例，这样配着文字，刚好可以使“按钮”呈正方形。<script type="text/javascript"></script>
