安卓动态增加按钮
首先了解一下LayouInflater类：将一个layout = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); public View inflate (int resource, ViewGroup root)Since: API Level 1Inflate a new view hierarchy from the specified if there is an error.Parametersresource ID for an this is the root View; otherwise it is the root of the inflated <? android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <Button android:id="@+id/newGuessButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" /> </LinearLayout> (guess_button.<TableLayout android:id="@+id/buttonTableLayout" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="1" android:stretchColumns="0,1,2" > <TableRow android:id="@+id/tableRow0" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> </TableRow> <TableRow android:id="@+id/tableRow1" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> </TableRow> <TableRow android:id="@+id/tableRow2" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> </TableRow> </TableLayout> (main.=(TableLayout) findViewById(R.id.buttonLayout);)现在我们将其第一行进行扩充：[java] view plaincopyLayoutInflater inflater = (LayoutInflater)context.getSystemService (Context.LAYOUT_INFLATER_SERVICE); Button newGuessButton =(Button)inflater.inflater(R.layout.guess_button,null); //获得按钮 newGuessButton.setText("abc"); //设置按钮文本 newGuessButton.setOnClickListener(guessButtonListener); //设置Listener (TableRow) buttonTableLayout.getChildAt(1); //将newGuessButton加到table第一行 OK 整个流程就完成了TAG:phone 开发
