目前我的代码显示线性布局
但我想这样显示
在这里我附上我的代码请尝试帮助
public class MainActivity extends Activity
{
LinearLayout MainLinearObj;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MainLinearObj = (LinearLayout) findViewById(R.id.MainLinear);
for(int i = 0; i < 3; i++)
{
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(100,100);
llp.setMargins(10, 10, 10, 10);
llp.weight = 1;
LinearLayout ll = new LinearLayout(MainActivity.this);
ll.setBackgroundColor(Color.RED);
ll.setLayoutParams(new LinearLayout.LayoutParams(100,100));
ll.setId(i);
MainLinearObj.addView(ll,llp);
}
}
}
user1566160 的编辑代码检查它并查看它的输出，如果我在 edittext 中输入 10，那么我需要总共 10 个正方形，因为每行的输出需要 3 个正方形
public class MainActivity extends Activity
{
LinearLayout MainLinearObj;
EditText et;
Button btn;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MainLinearObj = (LinearLayout) findViewById(R.id.MainLinear);
et = (EditText) findViewById(R.id.editText1);
btn = (Button) findViewById(R.id.button1);
// String str = et.getText().toString();
// int no = Integer.parseInt(str);
btn.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
String str = et.getText().toString();
int no = Integer.parseInt(str);
// TODO Auto-generated method stub
for(int j=0;j<no;j++)
{
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(100,100);
llp.setMargins(10, 10, 10, 10);
llp.weight = 1;
LinearLayout.LayoutParams llp1 = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
LinearLayout newLinearLayout = new LinearLayout(MainActivity.this);
newLinearLayout.setOrientation(LinearLayout.HORIZONTAL);
newLinearLayout.setLayoutParams(llp1);
for(int i = 0; i < 3; i++)
{
LinearLayout ll = new LinearLayout(MainActivity.this);
ll.setOrientation(LinearLayout.VERTICAL);
ll.setBackgroundColor(Color.RED);
ll.setLayoutParams(new LinearLayout.LayoutParams(100,100));
ll.setId(i);
newLinearLayout.addView(ll,llp);
}
MainLinearObj.addView(newLinearLayout);
}
}
});
}
}
