动态TextView | Android

Question

我有一个TextView，如果我在TextView中写入4，它应该在LinearLayout中创建四个TextView。我还没有尝试过任何东西，只是一个新手。

Answer 1

private void createTextView(int number){ 
    while (number>0){ 
     TextView lTextView = new TextView(this); 
     lTextView.setText("Android"); 
     mLinearLayout.addView(lTextView); 
     number--; 
    } 
} 

Answer 2

setContentView(R.layout.layout_with_linear_parent); 

parentLinear=(LinearLayout) this.findViewById(R.id.parent_linear); 

LayoutParams lparams = new LayoutParams(
    LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); 
TextView tv1=new TextView(this); 
TextView tv2=new TextView(this); 
TextView tv3=new TextView(this); 
TextView tv4=new TextView(this); 

tv1.setLayoutParams(lparams); 
tv2.setLayoutParams(lparams); 
tv3.setLayoutParams(lparams); 
tv4.setLayoutParams(lparams); 

tv1.setText("test 1"); 
tv2.setText("test 2"); 
tv3.setText("test 3"); 
tv4.setText("test 4"); 
this.parentLinear.addView(tv1); 
this.parentLinear.addView(tv2); 
this.parentLinear.addView(tv3); 
this.parentLinear.addView(tv4); 

很容易与LinearLayout中这样做，因为布局较少constraints.You可以做同样的事情RelativeLayout的，那么你将需要添加更多约束的LayoutParams
