所以我有一个已经填充了子项的线性布局.有没有办法改变其中一个孩子的位置？

如果有任何帮助的话,我正试图交换他们之间的观点.

final LinearLayout parrent = (LinearLayout)findViewById(R.id.llWidgetScreen);

final LinearLayout Delailah = new LinearLayout(this);

Delailah.setLayoutParams(new android.widget.LinearLayout.LayoutParams(android.view.ViewGroup.LayoutParams.FILL_PARENT, android.view.ViewGroup.LayoutParams.WRAP_CONTENT));

AppWidgetHostView wedgy = attachWidget(mAppWidgetHost.createView(this, appWidgetId, appWidgetInfo));

Delailah.addView(wedgy);

final Button btn = new Button(this);

btn.setLayoutParams(new android.widget.LinearLayout.LayoutParams((int)(20*scale +0.5f), android.view.ViewGroup.LayoutParams.FILL_PARENT, 0f));

btn.setOnLongClickListener(new OnLongClickListener() {

@Override

public boolean onLongClick(View v) {

parrent.removeView(Delailah);

return false;

}

});

btn.setBackgroundColor(mainColor);

btn.setText(parrent.getChildCount()+1+"");

btn.setTextColor(textColor);

btn.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

if(ReadyForDrag==0)

{

btn.setBackgroundColor(actiColor);

ReadyForDrag++;

DragPosition1=Integer.parseInt(btn.getText().toString());

}

else if(ReadyForDrag==1)

{

btn.setBackgroundColor(actiColor);

ReadyForDrag=0;

LinearLayout v1 = (LinearLayout)parrent.getChildAt(DragPosition1);

LinearLayout v2 = (LinearLayout)parrent.getChildAt(Integer.parseInt(btn.getText().toString()));

//move view 2 to position 1

//move view 1 to position 2

}

}

});

Delailah.addView(btn);

parrent.addView(Delailah);
