每個以前的請求重新措辭......我在運行時動態添加TableLayouts。視圖大綱看起來像這樣... LinearLayout-> ScrollView-> TableLayout->在運行時循環創建TableLayouts和TableRows。所以基本上我循環和增加以下內容：setBackgroundColor導致TableLayout對齊問題
爲（i = 0 ....我++）

現在一切都正確添加，看起來正確，並正確滾動。不過，我正在嘗試創建一個onTouch事件，它改變了動態創建的TableLayout上的背景。該onTouch每個動態創建的TableLayout裏面我有一個onTouch事件調用時執行以下操作：
tableLayoutRow1.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
Log.d("OnTouch", "OnTouch Event for " + Integer.toString(v.getId()) + " event:" + Integer.toString(event.getAction()));
switch(event.getAction())
{
case MotionEvent.ACTION_DOWN:
Log.d("OnTouch", "Changing to GREEN");
v.setBackgroundColor(Color.GRAY);
break;
case MotionEvent.ACTION_UP:
case MotionEvent.ACTION_MOVE:
Log.d("OnTouch", "Changing to BLACK");
v.setBackgroundColor(Color.BLACK);
break;
}
return true;
}
});
每當它調用它攪亂了動態創建TableLayouts的每一個的對齊setBackgroundColor，使它們看起來像此：

整個代碼如下。我希望現在這是清楚的。
public class TableActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
linearLayout.setWeightSum(1);
ScrollView scrollView = new ScrollView(this);
scrollView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
TableLayout tableLayoutMaster = new TableLayout(this);
tableLayoutMaster.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
// <table>
// <tr><td><table><tr><td></td><td></td><td></td></tr></table></td></tr>
// <tr><td></td></tr>
// </table>
for(int i=0; i<=30; i++)
{
TableLayout tableLayoutRow1 = new TableLayout(this);
tableLayoutRow1.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
tableLayoutRow1.setColumnStretchable(2, true);
//tableLayoutRow1.setBackgroundColor(Color.GREEN);
TableRow tableRow = new TableRow(this);
ImageView left_column = new ImageView(this);
left_column.setImageResource(17301550);
tableRow.addView(left_column);
TextView middle_column = new TextView(this);
middle_column.setText("Left Column:" + Integer.toString(i));
middle_column.setTypeface(null, Typeface.BOLD);
middle_column.setGravity(Gravity.LEFT);
middle_column.setPadding(5, 0, 0, 0);
tableRow.addView(middle_column);
TextView right_column = new TextView(this);
right_column.setText("Right Column:" + Integer.toString(i));
right_column.setTypeface(null, Typeface.BOLD);
right_column.setGravity(Gravity.RIGHT);
right_column.setPadding(0, 0, 5, 0);
tableRow.addView(right_column);
tableLayoutRow1.addView(tableRow);
tableRow = null;
// now for the bottom row
TextView bottom_column = new TextView(this);
bottom_column.setText("Starting activity com.developersinfo.testing.TableActivity on device emulator-5554");
bottom_column.setTextSize(12f);
bottom_column.setGravity(Gravity.LEFT);
bottom_column.setPadding(30, 0, 0, 0);
tableLayoutRow1.addView(bottom_column);
tableLayoutRow1.setId(i);
tableLayoutRow1.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
Log.d("OnFocusChange", "OnFocusChange Event for " + Integer.toString(v.getId()));
}
});
tableLayoutRow1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Log.d("OnClick", "OnClick Event for " + Integer.toString(v.getId()));
}
});
tableLayoutRow1.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
Log.d("OnTouch", "OnTouch Event for " + Integer.toString(v.getId()) + " event:" + Integer.toString(event.getAction()));
switch(event.getAction())
{
case MotionEvent.ACTION_DOWN:
Log.d("OnTouch", "Changing to GREEN");
v.setBackgroundColor(Color.GRAY);
break;
case MotionEvent.ACTION_UP:
case MotionEvent.ACTION_MOVE:
Log.d("OnTouch", "Changing to BLACK");
v.setBackgroundColor(Color.BLACK);
break;
}
return true;
}
});
// now add to master table
tableLayoutMaster.addView(tableLayoutRow1);
}
scrollView.addView(tableLayoutMaster);
linearLayout.addView(scrollView);
setContentView(linearLayout);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
}
我已經試過所有我能想到的，以防止它這樣做，但到目前爲止，我無法解釋爲何或如何糾正它。只要我不調用onTouch中的setBackgroundColor，所有內容都會按照預期滾動並對齊。
