Java 代码：
public class WRActivity extends Activity {
Button add_returns;
GridLayout show_warennt_returns;
EditText serial_no;
EditText reason;
EditText no_of_returns;
Button next;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_wr);
add_returns = (Button) findViewById(R.id.add_returns);
add_returns.setOnClickListener(oc);
no_of_returns = (EditText) findViewById(R.id.add_no_of_returns);
show_warennt_returns = (GridLayout) findViewById(R.id.returnshow);
}
OnClickListener oc = new OnClickListener() {
@Override
public void onClick(View v) {
Add_text();
}
};
public void Add_text() {
for (int i = 0; i < Integer
.parseInt(no_of_returns.getText().toString()); i++) {
GridLayout ll = new GridLayout(WRActivity.this);
ll.setOrientation(GridLayout.HORIZONTAL);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
ll.setColumnCount(2);
ll.setRowCount(2);
TextView serial = new TextView(WRActivity.this);
serial.setText("Serial No");
serial.setPadding(10, 10, 10, 10);
serial.setTag("weight");
ll.addView(serial);
serial_no = new EditText(WRActivity.this);
serial_no = new EditText(WRActivity.this);
serial_no.setPadding(10, 10, 10, 10);
serial_no.setWidth(300);
serial_no.setTag("Product_ID");
ll.addView(serial_no);
TextView serial1 = new TextView(WRActivity.this);
serial1.setText("Reason");
serial1.setPadding(10, 10, 10, 10);
serial1.setTag("weight");
ll.addView(serial1);
reason = new EditText(WRActivity.this);
reason.setPadding(10, 10, 10, 10);
reason.setTag("Product_ID");
reason.setWidth(300);
ll.addView(reason);
show_warennt_returns.addView(ll);
}
}
}
当在 EditText 中输入元素的编号时，我已经尝试使用上面的代码动态显示两个文本字段。
它很好，但如果我输入超过 10 个，它只显示前 10 个，只有其他的不会显示在网格布局上。
