流式布局

1.创建类继承LinearLayout  方法

// 得到整个屏幕的宽度

DisplayMetrics metrics = context.getResources().getDisplayMetrics();

pwidth = metrics.widthPixels;

setOrientation(VERTICAL);

public LinearLayout getlinearLayout() {

                LinearLayout linearLayout =new LinearLayout(getContext());

                LayoutParams params =new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

                linearLayout.setLayoutParams(params);

                this.addView(linearLayout);

                return linearLayout;

}

public TextView getTextView() {

        TextView textView =new TextView(getContext());

        textView.setTextSize(20);

        textView.setBackgroundResource(R.drawable.text);

        textView.setTextColor(Color.parseColor("#FF3D7EBF"));

        textView.setPadding(10,10,10,10);

        return textView;

}

public void getData(List data) {

        LinearLayout linearLayout = getlinearLayout();

        for (int i =0; i < data.size(); i++) {

            String temp = data.get(i);

            int linWidth =0;

            int count = linearLayout.getChildCount();

            for (int j =0; j < count; j++) {

                TextView textView = (TextView) linearLayout.getChildAt(j);

                LayoutParams params = (LayoutParams) textView.getLayoutParams();

                int leftMargin = params.leftMargin;

                textView.measure(getMeasuredWidth(), getMeasuredHeight());

                linWidth += textView.getMeasuredWidth() + leftMargin + textView.getPaddingLeft();

            }

            final TextView textView = getTextView();

            LayoutParams params = (LayoutParams)new LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,             ViewGroup.LayoutParams.WRAP_CONTENT);

            params.leftMargin =10;

            params.topMargin =2;

            textView.setLayoutParams(params);

            textView.setText(temp);

            textView.measure(getMeasuredWidth(),getMeasuredHeight());

            int textWidth = textView.getMeasuredWidth() + textView.getPaddingLeft() + textView.getPaddingRight();

            textView.setOnClickListener(new OnClickListener() {

            @Override

            public void onClick(View v) {

                    Toast.makeText(getContext(),textView.getText().toString()+"", Toast.LENGTH_SHORT).show();

            }

           });

    if(pwidth>=textWidth+linWidth){

        linearLayout.addView(textView);

    }else{

        linearLayout = getlinearLayout();

        linearLayout.addView(textView);

    }

    }
