我想在Android中平均分配Android中的TableRow空间。到目前为止,这是我完成的屏幕。
我希望“text 1 text 1 text 1”行占用相同的空间。我想从java代码中做到这一点。我的java代码如下:
public class History extends Activity implements View.OnClickListener {
int counter=0;
TableLayout TL ;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.history);
Button b1 = (Button) findViewById(R.id.Button01);
b1.setOnClickListener(this);
}
public void onClick(View arg0) {
TableLayout TL = (TableLayout) findViewById(R.id.table_layout);
TableRow row = new TableRow(this);
counter++;
TextView t = new TextView(this);
t.setText("text " + counter);
TextView t1 = new TextView(this);
t1.setText("text " + counter);
TextView t2 = new TextView(this);
t2.setText("text " + counter);
// add the TextView and the CheckBox to the new TableRow
row.addView(t);
row.addView(t1);
row.addView(t2);
TL.addView(row,new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
}
}
我想实现以下屏幕。 我能做些什么来实现我的目标?

您想在weight
中使用weightSum
和TableRow
,并通过TextView
设置TableLayout.LayoutParams
来执行此操作。以下是一些带有相关注释的示例代码:
TableRow row = new TableRow(this);
row.setLayoutParams(
new TableLayout.LayoutParams((LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT))
// Set the weightSum of the row
row.setWeightSum(1f);
// Set the layout and weight for the columns. Note 0.5f gives us 0.5f+0.5f = 1f,
// the weightSum set above. (Using two rows as an example).
TableLayout.LayoutParams layoutParams =
new TableLayout.LayoutParams(0,
LayoutParams.LayoutParams.WRAP_CONTENT, 0.5f);
TextView t1 = new TextView(this);
t1.setText("text " + counter);
// Set our layoutParams
t1.setLayoutParams(layoutParams);
TextView t2 = new TextView(this);
t2.setText("text " + counter);
// Set our layoutParams
t2.setLayoutParams(layoutParams);
// Add views to row
row.addView(t1);
row.addView(t2);
// Add row to table
TL.addView(row);
